This switches the compiler/ component to get compiled with
-XNoImplicitPrelude and a `import GhcPrelude` is inserted in all
modules.
This is motivated by the upcoming "Prelude" re-export of
`Semigroup((<>))` which would cause lots of name clashes in every
modulewhich imports also `Outputable`

We pretty-print a type by converting it to an IfaceType and
pretty-printing that. But
(a) that's a bit indirect, and
(b) delibrately loses information about (e.g.) the kind
on the /occurrences/ of a type variable
So this patch implements debugPprType, which pretty prints
the type directly, with no fancy formatting. It's just used
for debugging.
I took the opportunity to refactor the debug-pretty-printing
machinery a little. In particular, define these functions
and use them:
ifPprDeubug :: SDoc -> SDOc -> SDoc
-- Says what to do with and without -dppr-debug
whenPprDebug :: SDoc -> SDoc
-- Says what to do with -dppr-debug; without is empty
getPprDebug :: (Bool -> SDoc) -> SDoc
getPprDebug used to be called sdocPprDebugWith
whenPprDebug used to be called ifPprDebug
So a lot of files get touched in a very mechanical way

Summary:
Add prettyprinter tests, which take a file, parse it, pretty print it,
re-parse the pretty printed version and then compare the original and
new ASTs (ignoring locations)
Updates haddock submodule to match the AST changes.
There are three issues outstanding
1. Extra parens around a context are not reproduced. This will require an
AST change and will be done in a separate patch.
2. Currently if an `HsTickPragma` is found, this is not pretty-printed,
to prevent noise in the output.
I am not sure what the desired behaviour in this case is, so have left
it as before. Test Ppr047 is marked as expected fail for this.
3. Apart from in a context, the ParsedSource AST keeps all the parens from
the original source. Something is happening in the renamer to remove the
parens around visible type application, causing T12530 to fail, as the
dumped splice decl is after the renamer.
This needs to be fixed by keeping the parens, but I do not know where they
are being removed. I have amended the test to pass, by removing the parens
in the expected output.

Summary:
Deriving `Typeable` has been a no-op since GHC 7.10, and now that we
require 7.10+ to build GHC, we can remove all the redundant `deriving Typeable`
statements in GHC.

Summary:
In the past the canonical way for constructing an SDoc string literal was the
composition `ptext . sLit`. But for some time now we have function `text` that
does the same. Plus it has some rules that optimize its runtime behaviour.
This patch takes all uses of `ptext . sLit` in the compiler and replaces them
with calls to `text`. The main benefits of this patch are clener (shorter) code
and less dependencies between module, because many modules now do not need to
import `FastString`. I don't expect any performance benefits - we mostly use
SDocs to report errors and it seems there is little to be gained here.

Summary:
The strings used in a WARNING pragma are captured via
strings :: { Located ([AddAnn],[Located FastString]) }
: STRING { sL1 $1 ([],[L (gl $1) (getSTRING $1)]) }
..
The STRING token has a method getSTRINGs that returns the original
source text for a string.
A warning of the form
{-# WARNING Logic
, mkSolver
, mkSimpleSolver
, mkSolverForLogic
, solverSetParams
, solverPush
, solverPop
, solverReset
, solverGetNumScopes
, solverAssertCnstr
, solverAssertAndTrack
, solverCheck
, solverCheckAndGetModel
, solverGetReasonUnknown
"New Z3 API support is still incomplete and fragile: \
\you may experience segmentation faults!"
#-}
returns the concatenated warning string rather than the original source.
This patch now deals with all remaining instances of getSTRING to bring
in a SourceText for each.
This updates the haddock submodule as well, for the AST change.

Summary:
Add a reference note to each AnnKeywordId haddock comment so GHC
developers will have an idea why they are there.
Add a new test to ghc-api/annotations to serve as a template for other
GHC developers when they need to update the parser. It provides output
which checks that each SrcSpan that an annotation is attached to
actually appears in the `ParsedSource`, and lists the individual
annotations. The idea is that a developer writes a version of this
which parses a sample file using whatever syntax is changed in
Parser.y, and can then check that all the annotations come through.
Depends on D538

Summary:
HsTyLit now has SourceText
Update documentation of HsSyn to reflect which annotations are attached to which element.
Ensure that the parser always keeps HsSCC and HsTickPragma values, to
be ignored in the desugar phase if not needed
Bringing in SourceText for pragmas
Add Location in NPlusKPat
Add Location in FunDep
Make RecCon payload Located
Explicitly add AnnVal to RdrName where it is compound
Add Location in IPBind
Add Location to name in IEThingAbs
Add Maybe (Located id,Bool) to Match to track fun_id,infix
This includes converting Match into a record and adding a note about why
the fun_id needs to be replicated in the Match.
Add Location in KindedTyVar
Sort out semi-colons for parsing
- import statements
- stmts
- decls
- decls_cls
- decls_inst
This updates the haddock submodule.
