Use UnitId in the backend instead of Unit
In Cmm we can only have real units identified with an UnitId. Other
units (on-the-fly instantiated units and holes) are only used in
type-checking backpack sessions that don't produce Cmm.

rts: fix race condition in StgCRun
On windows the stack has to be allocated 4k at a time, otherwise we get
a segfault. This is done by using a helper ___chkstk_ms that is provided
by libgcc. The Haskell side already knows how to handle this but we need
to do the same from STG. Previously we would drop the stack in StgRun
but would only make it valid whenever the scheduler loop ran.
This approach was fundamentally broken in that it falls apart when you
take a signal from the OS. We see it less often because you initially
get allocated a 1MB stack block which you have to blow past first.
Concretely this means we must always keep the stack valid.
Fixes #18601.

Expose RTS-only ways (#18651)
Some RTS ways are exposed via settings (ghcThreaded, ghcDebugged) but
not all. It's simpler if the RTS exposes them all itself.

Use proper RTS flags when collecting residency in perf tests.
Replace options like collect_stats(['peak_megabytes_allocated'],4) with
collect_runtime_residency(4) and so forth. Reason being that the later
also supplies some default RTS arguments which make sure residency does
not fluctuate too much.
The new flags mean we get new (hopefully more accurate) baselines so
accept the stat changes.

testsuite/timeout: Fix windows specific errors.
We now seem to use -Werror there. Which caused some long standing
warnings to become errors.
I applied changes to remove the warnings allowing the testsuite to
run on windows as well.

Bignum: match on small Integer/Natural
Previously we only matched on *variables* whose unfoldings were a ConApp
of the form `IS lit#` or `NS lit##`. But we forgot to match on the
ConApp directly... As a consequence, constant folding only worked after
the FloatOut pass which creates bindings for most sub-expressions. With
this patch, matching on bignums works even with -O0 (see bignumMatch
test).

ApiAnnotations : preserve parens in GADTs
A cleanup in 7f418acf61e accidentally discarded some parens in
ConDeclGADT.
Make sure these stay in the AST in a usable format.
Also ensure the AnnLolly does not get lost in a GADT.

Fix desugaring of record updates on data families
This fixes a long-standing bug in the desugaring of record
updates for data families, when the latter involves a GADT. It's
all explained in Note [Update for GADTs] in GHC.HsToCore.Expr.
Building the correct cast is surprisingly tricky, as that Note
explains.
Fixes #18809. The test case (in indexed-types/should_compile/T18809)
contains several examples that exercise the dark corners.

Add TyCon Set/Env and use them in a few places.
Firstly this improves code clarity.
But it also has performance benefits as we no longer
go through the name of the TyCon to get at it's unique.
In order to make this work the recursion check for TyCon
has been moved into it's own module in order to avoid import
cycles.

Proof of Concept implementation of in-tree API Annotations
This MR introduces a possible machinery to introduce API Annotations
into the TTG extension points.
It is intended to be a concrete example for discussion.
It still needs to process comments.
----
Work in progress, adding more TTG extensions for annotations.
And fixing ppr round-trip tests by being able to blank out in-tree
annotations, as done with SrcSpans.
This is needed for the case of
class Foo a where
for which current ppr does not print the "where".
Rename AA to AddApiAnn and AA to AddAnn
Add XConPatIn and XConPatOut
Rebase
----
First pass at bringing in LocatedA for API anns in locations
Treatment of ECP in parsing is provisional at this stage, leads to some
horribly stuff in Parser.y and RdrHsSyn.
It is an extensive but not invasive change. I think (AZ).
Locally it reports some parsing tests using less memory.
Add ApiAnns to the HsExpr data structure.
rebase.
Change HsMatchContext and HsStmtContext to use an id, not a GhcPass
parameter.
Add ApiAnns to Hs/Types
Rebase
Rebased 2020-03-25
WIP on in-tree annotations
Includes updating HsModule
Imports
LocateA ImportDecl so we can hang AnnSemi off it
A whole bunch of stuff more
InjectivityAnn and FamEqn now have annotations in them
Add annotations to context srcspan
----
In-tree annotations: LHsDecl and LHsBind LocatedA
----
WIP on in-tree annotations
----
in-tree annotations: LHsType is now LocatedA
----
FunDeps is now also a HS data type
----
WIP. Added LocatedA to Pat, Expr, Decl
And worked some more through Parser.y
----
LStmt now Located
----
Finished working through Parser.y, tests seem ok
failures relate to annotations.
Adding test infrastructure for check-exact
Like check-ppr, but checking for an exact reproduction of the parsed
source file.
Starting to work on actual exact printer
Bring in ApiAnnName
As an alternative for LocatedA, to be used for names only.
Carrying extra name adornments, such as locations of backticks,
parens, etc.
Working on changing ApiAnnName to accurately reflect actual usage
Get rid of AnnApiName in favour of LocatedN
Working on check-exact. Making progress
Working on the ghc-exact bit
Progress, can reproduce the first Test.hs file.
Move API Annotations out of the extensions to annotations
Remove LHsLocalBinds
Fix up after rebasing to bring in XRec
Main thing is to make
type instance XRec (GhcPass p) a = GenLocated (Anno a) a
type family Anno a = b
But this has massive implications.
