Restore the --coerce option in 'happy' configuration
happy-1.19.10 has been released with a fix for --coerce in the presence
of higher rank types. This should result in about 10% performance
improvement in the parser.

Hadrian: 'need' source files for various docs in Rules.Documentation
Previously, changing one of the .rst files from the user guide would not cause
the user guide to be rebuilt. This patch take a first stab at declaring the
documentation source files that our documentation rules depend on, focusing
on the .rst files only for now.
We eventually might want to rebuild docs when we, say, change the haddock style
file, but this level of tracking isn't really necessary for now.
This fixes #16645.

Improve test runner logging when calculating performance metric baseline #16662
We attempt to get 75 commit hashes via `git log`, but this only gave 10
hashes in a CI run (see #16662). Better logging may help solve this
error if it occurs again in the future.

Refactor Libffi and RTS rules
This removes a hack that copies libffi files to the rts
build directory. This was done in a libffi rule, but now
an rts rule correctly needs and copies the relevant
files from the libffi build dir to the rts build dir.
Issues: #16272 #16304

distrib/configure.ac.in: remove mention to 'settings', since settings.in is gone
Otherwise, when `./configure`ing a GHC bindist, produced by either Make or
Hadrian, we would try to generate the `settings` file from the `settings.in`
template that we used to have around but which has been gone since d37d91e9.
That commit generates the settings file using the build systems instead, but
forgot to remove this mention to the `settings` file.

Fix #16666 by parenthesizing contexts in Convert
Most places where we convert contexts in `Convert` are actually in
positions that are to the left of some `=>`, such as in superclasses
and instance contexts. Accordingly, these contexts need to be
parenthesized at `funPrec`. To accomplish this, this patch changes
`cvtContext` to require a precedence argument for the purposes of
calling `parenthesizeHsContext` and adjusts all `cvtContext` call
sites accordingly.

Have GHCi use object code for UnboxedTuples modules #15454
The idea is to automatically enable -fobject-code for modules that use
UnboxedTuples, along with all the modules they depend on. When looking
into how to solve this, I was pleased to find that there was already
highly similar logic for enabling code generation when -fno-code is
specified but TemplateHaskell is used.
The state before this patch was that if you used unboxed tuples then you
had to enable `-fobject-code` globally rather than on a per module
basis.

RTS: Fix restrictive cast
Commit e75a9afd2989e0460f9b49fa07c1667299d93ee9 added an `unsigned` cast
to account for OSes that have signed `rlim_t` signed. Unfortunately,
the `unsigned` cast has the unintended effect of narrowing `rlim_t` to
only 4 bytes. This leads to some spurious out of memory crashes
(in particular: Haddock crashes with OOM whenn building docs of
`ghc`-the-library).
In this case, `W_` is a better type to cast to: we know it will be
unsigned too and it has the same type as `*len` (so we don't suffer from
accidental narrowing).

Hadrian: add --test-root-dirs, to only run specific directories of tests
We can specify several of those, by using the flag multiple times or
just once but combining the directories with ':'.
Along the way, this patch also fixes the testsuite-related --only flag,
so that we can use it many times instead of being force to specify a
space-separated list of test in a single --only flag.

Use HsTyPats in associated type family defaults
Associated type family default declarations behave strangely in a
couple of ways:
1. If one tries to bind the type variables with an explicit `forall`,
the `forall`'d part will simply be ignored. (#16110)
2. One cannot use visible kind application syntax on the left-hand
sides of associated default equations, unlike every other form
of type family equation. (#16356)
Both of these issues have a common solution. Instead of using
`LHsQTyVars` to represent the left-hand side arguments of an
associated default equation, we instead use `HsTyPats`, which is what
other forms of type family equations use. In particular, here are
some highlights of this patch:
* `FamEqn` is no longer parameterized by a `pats` type variable, as
the `feqn_pats` field is now always `HsTyPats`.
* The new design for `FamEqn` in chronicled in
`Note [Type family instance declarations in HsSyn]`.
* `TyFamDefltEqn` now becomes the same thing as `TyFamInstEqn`. This
means that many of `TyFamDefltEqn`'s code paths can now reuse the
code paths for `TyFamInstEqn`, resulting in substantial
simplifications to various parts of the code dealing with
associated type family defaults.
Fixes #16110 and #16356.

add an --hadrian mode to ./validate
When the '--hadrian' flag is passed to the validate script, we use hadrian
to build GHC, package it up in a binary distribution and later on run GHC's
testsuite against the said bindist, which gets installed locally in the process.
Along the way, this commit fixes a typo, an omission (build iserv binaries
before producing the bindist archive) and moves the Makefile that enables
'make install' on those bindists from being a list of strings in the code to
an actual file (it was becoming increasingly annoying to work with).
Finally, the Settings.Builders.Ghc part of this patch is necessary for being
able to use the installed binary distribution, in 'validate'.

Some forall-related cleanup in deriving code
* Tweak the parser to allow `deriving` clauses to mention explicit
`forall`s or kind signatures without gratuitous parentheses.
(This fixes #14332 as a consequence.)
* Allow Haddock comments on `deriving` clauses with explicit
`forall`s. This requires corresponding changes in Haddock.

Add PlainPanic for throwing exceptions without depending on pprint
This commit splits out a subset of GhcException which do not depend on
pretty printing (SDoc), as a new datatype called
PlainGhcException. These exceptions can be caught as GhcException,
because 'fromException' will convert them.
The motivation for this change is that that the Panic module
transitively depends on many modules, primarily due to pretty printing
code. It's on the order of about 130 modules. This large set of
dependencies has a few implications:
1. To avoid cycles / use of boot files, these dependencies cannot
throw GhcException.
2. There are some utility modules that use UnboxedTuples and also use
`panic`. This means that when loading GHC into GHCi, about 130
additional modules would need to be compiled instead of
interpreted. Splitting the non-pprint exception throwing into a new
module resolves this issue. See #13101

Hadrian: Add Mising Libffi Dependencies #16653
Libffi is ultimately built from a single archive file (e.g.
libffi-tarballs/libffi-3.99999+git20171002+77e130c.tar.gz).
The file can be seen as the shallow dependency for the whole
libffi build. Hence, in all libffi rules, the archive is
`need`ed and the build directory is `trackAllow`ed.

Let the specialiser work on dicts under lambdas
Following the discussion under #16473, this change allows the
specializer to work on any dicts in a lambda, not just those that occur
at the beginning.
For example, if you use data types which contain dictionaries and
higher-rank functions then once these are erased by the optimiser you
end up with functions such as:
```
go_s4K9
Int#
-> forall (m :: * -> *).
Monad m =>
(forall x. Union '[State (Sum Int)] x -> m x) -> m ()
```
The dictionary argument is after the Int# value argument, this patch
allows `go` to be specialised.

Lowercase windows imports
While windows and macOS are currently on case-insensitive file
systems, this poses no issue on those. When cross compiling from
linux with a case sensitive file system and mingw providing only
lowercase headers, this in fact produces an issue. As such we just
lowercase the import headers, which should still work fine on a
case insensitive file system and also enable mingw's headers to
be usable porperly.

Hadrian: Fix problem with unlit path in settings file
e529c65e introduced a problem in the logic for generating the
path to the unlit command in the settings file, and this patches
fixes it.
This fixes many tests, the simplest of which is:
> _build/stage1/bin/ghc testsuite/tests/parser/should_fail/T8430.lhs
which failed because of a wrong path for unlit, and now fails for the right
reason, with the error message expected for this test.
This addresses #16659.

Fix padding of entries in .prof files
When the number of entries of a cost centre reaches 11 digits, it takes
up the whole space reserved for it and the prof file ends up looking
like:
... no. entries %time %alloc %time %alloc
...
... 120918 978250 0.0 0.0 0.0 0.0
... 118891 0 0.0 0.0 73.3 80.8
... 11890229702412351 8.9 13.5 73.3 80.8
... 118903 153799689 0.0 0.1 0.0 0.1
...
This results in tooling not being able to parse the .prof file. I
realise we have the JSON output as well now, but still it'd be good to
fix this little weirdness.
Original bug report and full prof file can be seen here:

least stage1 linking on macOS, but probably loads of other things too.
