rts: Explicit state that CONSTR tag field is zero-based

This was a bit unclear as we use both one-based and zero-based
tags in GHC.

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.

users-guide: Fix directive errors on 8.10

The following sections are not displayed due to a directive error:

  * -Wunused-record-wildcards
  * -Wredundant-record-wildcards

I changed the location of the `since` directive.

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.

It has caused an increase in variance of performance test T9630,

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.

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.
