Currently the `$make` variable is used without being set in `validate`'s
Hadrian path, which uses make to install the binary distribution. Fix
this.

There were various issues with testing the stage1 compiler..
1. The wrapper was not being built
2. The wrapper was picking up the stage0 package database and trying to
load prelude from that.
3. The wrappers never worked on windows so just don't support that for
now.
Fixes #21072

clock_gettime reports the combined total or user AND system time so in
order to replicate it with getrusage we need to add both system and user
time together.

This patch refactors hasFixedRuntimeRep_remainingValArgs, renaming it
to tcRemainingValArgs. The logic is moved to rebuildHsApps, which
ensures consistent behaviour across tcApp and quickLookArg1/tcEValArg.
This patch also refactors the treatment of stupid theta for data
constructors, changing the place we drop stupid theta arguments
from dsConLike to mkDataConRep (now the datacon wrapper drops these
arguments).
We decided not to implement PHASE 2 of the FixedRuntimeRep plan for
these remaining ValArgs. Future directions are outlined on the wiki:
https://gitlab.haskell.org/ghc/ghc/-/wikis/Remaining-ValArgs
Fixes #21544 and #21650

We used to process the rhs of non-recursive bindings and their body
using the same env. If we had something like
let x = ... x ...
this caused trouble because the two xs refer to different binders
but we would substitute both for a new binder x2 causing out of scope
errors.
We now simply use two different envs for the rhs and body in cse_bind.
It's all explained in the Note [Separate envs for let rhs and body]
Fixes #21685

It is redundant information and a source of needless version control
conflicts when multiple MRs are changing the deps list.
Just printing the list and not also its length is fine.

In the Specialiser, we missed one more call to
bringFloatedDictsIntoScope (see #21391).
This omission led to #21689. The problem is that the call
to `rewriteClassOps` needs to have in scope any dictionaries
floated out of the arguments we have just specialised.
Easy fix.

This commit fixes #20312
It deprecates "TypeInType" extension
according to the following proposal:
https://github.com/ghc-proposals/ghc-proposals/blob/master/proposals/0083-no-type-in-type.rst
It has been already implemented.
The migration strategy:
1. Disable TypeInType
2. Enable both DataKinds and PolyKinds extensions

As proposed in
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7508#note_432877 and
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7508#note_434676,
`GHC.HsToCore.Ticks` is about ticks, breakpoints are separate and
backend-specific (only for the bytecode interpreter), and mix entry
writing is just for HPC.
With this split we separate out those interpreter- and HPC-specific
its, and keep the main `GHC.HsToCore.Ticks` agnostic.
Also, instead of passing the reversed list and count around, we use
`SizedSeq` which abstracts over the algorithm. This is much nicer to
avoid noise and prevents bugs.
(The bugs are not just hypothetical! I missed up the reverses on an
earlier draft of this commit.)

The old name made it confusing why disabling HPC didn't disable the
entire pass. The name makes it clear --- there are other reasons to add
ticks in addition.

No need to inline traversing a maybe for `mkModBreaks`. And better to
make each function do one thing and let the caller deside when than
scatter the decision making and make the caller seem more imperative.

Since we started producing source dists with hadrian we stopped copying
in the files created by ./boot which adds a dependency on python3 and
autoreconf. This adds back in the files which were created by running
configure.

Switch to a pure Haskell implementation of base:GHC.Unicode, based on the implementation of the package unicode-data (https://github.com/composewell/unicode-data/).
Approved by CLC as per https://github.com/haskell/core-libraries-committee/issues/59#issuecomment-1132106691.
- Remove current Unicode cbits.
- Add generator for Unicode property files from Unicode Character Database.
- Generate internal modules.
- Update GHC.Unicode.
- Add unicode003 test for general categories and case mappings.
- Add Python scripts to check 'base' Unicode tests outputs and characters properties.

This commit redefines the structure of Splices in the AST.
We get rid of `HsSplice` which used to represent typed and untyped
splices, quasi quotes, and the result of splicing either an expression,
a type or a pattern.
Instead we have `HsUntypedSplice` which models an untyped splice or a
quasi quoter, which works in practice just like untyped splices.
The `HsExpr` constructor `HsSpliceE` which used to be constructed with
an `HsSplice` is split into `HsTypedSplice` and `HsUntypedSplice`. The
former is directly constructed with an `HsExpr` and the latter now takes
an `HsUntypedSplice`.
Both `HsType` and `Pat` constructors `HsSpliceTy` and `SplicePat` now
take an `HsUntypedSplice` instead of a `HsSplice` (remember only
/untyped splices/ can be spliced as types or patterns).
The result of splicing an expression, type, or pattern is now
comfortably stored in the extension fields `XSpliceTy`, `XSplicePat`,
`XUntypedSplice` as, respectively, `HsUntypedSpliceResult (HsType
GhcRn)`, `HsUntypedSpliceResult (Pat GhcRn)`, and `HsUntypedSpliceResult
(HsExpr GhcRn)`
Overall the TTG extension points are now better used to
make invalid states unrepresentable and model the progression between
stages better.
See Note [Lifecycle of an untyped splice, and PendingRnSplice]
and Note [Lifecycle of an typed splice, and PendingTcSplice] for more
details.

too hard
Progress towards #17957
Because of `CoreM`, I did not move the `DynFlags` and `HscEnv` to other
modules as thoroughly as I usually do. This does mean that risk of
`DynFlags` "creeping back in" is higher than it usually is.
After we do the same process to the other Core passes, and then figure
out what we want to do about `CoreM`, we can finish the job started
here.
That is a good deal more work, however, so it certainly makes sense to
land this now.

These executables (such as hsc2hs) are built using the boot compiler and
crucially, most libraries from the global package database.
We also move other build-time executables to be built in this stage such
as linters which also cleans up which libraries end up in the global
package database. This allows us to remove hacks where linters-common is
removed from the package database when a bindist is created.
This fixes issues caused by infinite recursion due to bytestring adding
a dependency on template-haskell.

Now #21563 is fixed we can properly enable `-dlint` in CI rather than a
subset of the flags.

We originally planned to remove the flag in 9.4 but there's actually no
great rush to do so and it's probably less confusing (forever) to keep
the message around suggesting an explicit profiling option.

This fixes two bugs which were adding dependencies on alex/happy when
building from a source dist.
* When we try to pass `--with-alex` and `--with-happy` to cabal when
configuring but the builders are not set. This is fixed by making them
optional.
* When we configure, cabal requires alex/happy because of the
build-tool-depends fields. These are now made optional with a cabal
flag (build-tool-depends) for compiler/hpc-bin/genprimopcode.
