Add Generic tuple instances up to 15-tuple

Why 15? Because we have Eq instances up to 15.

Metric Increase:

Hadrian: programs need registered ghc-pkg libraries

In Hadrian, building programs (e.g. `ghc` or `haddock`) requires libraries located in the ghc-pkg package database i.e.

    _build/stage1/lib/x86_64-linux-ghc-8.9.0.20190430/libHSdeepseq-1.4.4.0-ghc8.9.0.20190430.so

Add the corresponding `need`s for these library files and the subsequent rules.

Remove all target-specific portions of Config.hs

1. If GHC is to be multi-target, these cannot be baked in at compile
   time.

2. Compile-time flags have a higher maintenance than run-time flags.

3. The old way makes build system implementation (various bootstrapping
   details) with the thing being built. E.g. GHC doesn't need to care
   about which integer library *will* be used---this is purely a crutch
   so the build system doesn't need to pass flags later when using that
   library.

4. Experience with cross compilation in Nixpkgs has shown things work
   nicer when compiler's can *optionally* delegate the bootstrapping the
   package manager. The package manager knows the entire end-goal build
   plan, and thus can make top-down decisions on bootstrapping. GHC can
   just worry about GHC, not even core library like base and ghc-prim!

Guard CUSKs behind a language pragma

GHC Proposal #36 describes a transition plan away from CUSKs and to
top-level kind signatures:

1. Introduce a new extension, -XCUSKs, on by default, that detects CUSKs
   as they currently exist.
2. We turn off the -XCUSKs extension in a few releases and remove it
   sometime thereafter.

This patch implements phase 1 of this plan, introducing a new language
extension to control whether CUSKs are enabled. When top-level kind
signatures are implemented, we can transition to phase 2.

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.

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.
