Before this patch Integer and Natural literals were desugared into "real"
Core in Core prep. Now we desugar them directly into their final ConApp
form in HsToCore. We only keep the double representation for BigNat#
(literals larger than a machine Word/Int) which are still desugared in
Core prep.
Using the final form directly allows case-of-known-constructor to fire
for bignum literals, fixing #20245.
Slight increase (+2.3) in T4801 which is a pathological case with
Integer literals.

In order to make the packages in this repo "reinstallable", we need to
associate source code with a specific packages. Having a top level
`/includes` dir that mixes concerns (which packages' includes?) gets in
the way of this.
To start, I have moved everything to `rts/`, which is mostly correct.
There are a few things however that really don't belong in the rts (like
the generated constants haskell type, `CodeGen.Platform.h`). Those
needed to be manually adjusted.
Things of note:
- No symlinking for sake of windows, so we hard-link at configure time.
- `CodeGen.Platform.h` no longer as `.hs` extension (in addition to
being moved to `compiler/`) so as not to confuse anyone, since it is
next to Haskell files.
- Blanket `-Iincludes` is gone in both build systems, include paths now
more strictly respect per-package dependencies.
- `deriveConstants` has been taught to not require a `--target-os` flag
when generating the platform-agnostic Haskell type. Make takes
advantage of this, but Hadrian has yet to.

* For primops from `GHC.Prim` lookup the HValues in `GHC.PrimopWrappers`.
* Add short error messages if a user tries to use a *Non-Id* value or a
`pseudoop` in a `:print`, `:sprint` or `force`command.
* Add additional test cases for `Magic Ids`.

The stg_ctoi_t and stg_ret_t procedures which convert unboxed
tuples between the bytecode an native calling convention were
causing a panic when using the LLVM backend.

There is no reason to use CPP. __LINE__ and __FILE__ macros are now
better replaced with GHC's CallStack. As a bonus, assert error messages
now contain more information (function name, column).
Here is the mapping table (HasCallStack omitted):
* ASSERT: assert :: Bool -> a -> a
* MASSERT: massert :: Bool -> m ()
* ASSERTM: assertM :: m Bool -> m ()
* ASSERT2: assertPpr :: Bool -> SDoc -> a -> a
* MASSERT2: massertPpr :: Bool -> SDoc -> m ()
* ASSERTM2: assertPprM :: m Bool -> SDoc -> m ()

The loader state was stored into HscEnv. As we need to have two
interpreters and one loader state per interpreter in #14335, it's
natural to make the loader state a field of the Interp type.
As a side effect, many functions now only require a Interp parameter
instead of HscEnv. Sadly we can't fully free GHC.Linker.Loader of HscEnv
yet because the loader is initialised lazily from the HscEnv the first
time it is used. This is left as future work.
HscEnv may not contain an Interp value (i.e. hsc_interp :: Maybe Interp).
So a side effect of the previous side effect is that callers of the
modified functions now have to provide an Interp. It is satisfying as it
pushes upstream the handling of the case where HscEnv doesn't contain an
Interpreter. It is better than raising a panic (less partial functions,
"parse, don't validate", etc.).

Alt, AnnAlt and IfaceAlt were using triples. This patch makes them use
dedicated types so that we can try to make some fields strict (for
example) in the future.

This patch fixes #19133 by using LitRubbish for strict constructor
fields, even if they are of lifted types. Previously LitRubbish
worked only for unlifted (but boxed) types.
The change is very easy, although I needed a boolean field in
LitRubbish to say whether or not it is lifted. (That seemed easier
than giving it another type argument.
This is preparing for Andreas's work on establishing the invariant
that strict constructor fields are always tagged and evaluated
(see #16970).
Meanwhile, nothing was actually wrong before, so there are no tests.

This replaces all Word<N> = W<N># Word# and Int<N> = I<N># Int# with
Word<N> = W<N># Word<N># and Int<N> = I<N># Int<N>#, thus providing us
with properly sized primitives in the codegenerator instead of pretending
they are all full machine words.
This came up when implementing darwinpcs for arm64. The darwinpcs reqires
us to pack function argugments in excess of registers on the stack. While
most procedure call standards (pcs) assume arguments are just passed in
8 byte slots; and thus the caller does not know the exact signature to make
the call, darwinpcs requires us to adhere to the prototype, and thus have
the correct sizes. If we specify CInt in the FFI call, it should correspond
to the C int, and not just be Word sized, when it's only half the size.
This does change the expected output of T16402 but the new result is no
less correct as it eliminates the narrowing (instead of the `and` as was
previously done).
Bumps the array, bytestring, text, and binary submodules.

I was working on making DynFlags stateless (#17957), especially by
storing loaded plugins into HscEnv instead of DynFlags. It turned out to
be complicated because HscEnv is in GHC.Driver.Types but LoadedPlugin
isn't: it is in GHC.Driver.Plugins which depends on GHC.Driver.Types. I
didn't feel like introducing yet another hs-boot file to break the loop.
Additionally I remember that while we introduced the module hierarchy
(#13009) we talked about splitting GHC.Driver.Types because it contained
various unrelated types and functions, but we never executed. I didn't
feel like making GHC.Driver.Types bigger with more unrelated Plugins
related types, so finally I bit the bullet and split GHC.Driver.Types.
As a consequence this patch moves a lot of things. I've tried to put
them into appropriate modules but nothing is set in stone.
Several other things moved to avoid loops.
* Removed Binary instances from GHC.Utils.Binary for random compiler
things
* Moved Typeable Binary instances into GHC.Utils.Binary.Typeable: they
import a lot of things that users of GHC.Utils.Binary don't want to
depend on.
* put everything related to Units/Modules under GHC.Unit:
GHC.Unit.Finder, GHC.Unit.Module.{ModGuts,ModIface,Deps,etc.}
* Created several modules under GHC.Types: GHC.Types.Fixity, SourceText,
etc.
* Split GHC.Utils.Error (into GHC.Types.Error)
* Finally removed GHC.Driver.Types
Note that this patch doesn't put loaded plugins into HscEnv. It's left
for another patch.

Platform constant wrappers took a DynFlags parameter, hence implicitly
used the target platform constants. We removed them to allow support
for several platforms at once (#14335) and to avoid having to pass
the full DynFlags to every function (#17957).

This patch fixes the bug and implements the feature request of #3000.
1. If `Module` is a real module name and `identifier` a name of a
top-level function in `Module` then `:break Module.identifer` works
also for an `identifier` that is out of scope.
2. Extend the syntax for `:break identifier` to:
:break [ModQual.]topLevelIdent[.nestedIdent]...[.nestedIdent]
`ModQual` is optional and is either the effective name of a module or
the local alias of a qualified import statement.
`topLevelIdent` is the name of a top level function in the module
referenced by `ModQual`.
`nestedIdent` is optional and the name of a function nested in a let or
where clause inside the previously mentioned function `nestedIdent` or
`topLevelIdent`.
If `ModQual` is a module name, then `topLevelIdent` can be any top level
identifier in this module. If `ModQual` is missing or a local alias of a
qualified import, then `topLevelIdent` must be in scope.
Breakpoints can be set on arbitrarily deeply nested functions, but the
whole chain of nested function names must be specified.
3. To support the new functionality rewrite the code to tab complete `:break`.

tablesNextToCode is a platform setting and doesn't belong into DynFlags
(#17957). Doing this is also a prerequisite to fix #14335 where we deal
with two platforms (target and host) that may have different platform
settings.

Thanks to ghc-bignum, the compiler can be simplified:
* Types and constructors of Integer and Natural can be wired-in. It
means that we don't have to query them from interfaces. It also means
that numeric literals don't have to carry their type with them.
* The same code is used whatever ghc-bignum backend is enabled. In
particular, conversion of bignum literals into final Core expressions
is now much more straightforward. Bignum closure inspection too.
* GHC itself doesn't depend on any integer-* package anymore
* The `integerLibrary` setting is gone.

This is the first step towards implementation of the linear types proposal
(https://github.com/ghc-proposals/ghc-proposals/pull/111).
It features
* A language extension -XLinearTypes
* Syntax for linear functions in the surface language
* Linearity checking in Core Lint, enabled with -dlinear-core-lint
* Core-to-core passes are mostly compatible with linearity
* Fields in a data type can be linear or unrestricted; linear fields
have multiplicity-polymorphic constructors.
If -XLinearTypes is disabled, the GADT syntax defaults to linear fields
The following items are not yet supported:
* a # m -> b syntax (only prefix FUN is supported for now)
* Full multiplicity inference (multiplicities are really only checked)
* Decent linearity error messages
* Linear let, where, and case expressions in the surface language
(each of these currently introduce the unrestricted variant)
* Multiplicity-parametric fields
* Syntax for annotating lambda-bound or let-bound with a multiplicity
* Syntax for non-linear/multiple-field-multiplicity records
* Linear projections for records with a single linear field
* Linear pattern synonyms
* Multiplicity coercions (test LinearPolyType)
A high-level description can be found at
https://ghc.haskell.org/trac/ghc/wiki/LinearTypes/Implementation
Following the link above you will find a description of the changes made to Core.

Now since we no longer try to predict CAFfyness we have no need for the
solution to #16846. Eta expanding unsaturated primop applications is
conceptually simpler, especially in the presence of levity polymorphism.
This essentially reverts cac8dc9f51e31e4c0a6cd9bc302f7e1bc7c03beb,
as suggested in #18079.
Closes #18079.

Over the years the unit management code has been modified a lot to keep
up with changes in Cabal (e.g. support for several library components in
the same package), to integrate BackPack, etc. I found it very hard to
understand as the terminology wasn't consistent, was referring to past
concepts, etc.
The terminology is now explained as clearly as I could in the Note
"About Units" and the code is refactored to reflect it.
-------------------
Many names were misleading: UnitId is not an Id but could be a virtual
unit (an indefinite one instantiated on the fly), IndefUnitId
constructor may contain a definite instantiated unit, etc.
* Rename IndefUnitId into InstantiatedUnit
* Rename IndefModule into InstantiatedModule
* Rename UnitId type into Unit
* Rename IndefiniteUnitId constructor into VirtUnit
* Rename DefiniteUnitId constructor into RealUnit
* Rename packageConfigId into mkUnit
* Rename getPackageDetails into unsafeGetUnitInfo
* Rename InstalledUnitId into UnitId
Remove references to misleading ComponentId: a ComponentId is just an
indefinite unit-id to be instantiated.
* Rename ComponentId into IndefUnitId
* Rename ComponentDetails into UnitPprInfo
* Fix display of UnitPprInfo with empty version: this is now used for
units dynamically generated by BackPack
Generalize several types (Module, Unit, etc.) so that they can be used
with different unit identifier types: UnitKey, UnitId, Unit, etc.
* GenModule: Module, InstantiatedModule and InstalledModule are now
instances of this type
* Generalize DefUnitId, IndefUnitId, Unit, InstantiatedUnit,
PackageDatabase
Replace BackPack fake "hole" UnitId by a proper HoleUnit constructor.
Add basic support for UnitKey. They should be used more in the future to
avoid mixing them up with UnitId as we do now.
Add many comments.

Summary:
- There is no more use of the TABLES_NEXT_TO_CODE CPP macro in
`compiler/`. GHCI_TABLES_NEXT_TO_CODE is also removed entirely.
The field within `PlatformMisc` within `DynFlags` is used instead.
- The field is still not exposed as a CLI flag. We might consider some
way to ensure the right RTS / libraries are used before doing that.
