template-haskell: Move wired-ins to ghc-internal
Teo Camarasu authored 
Thus we make `template-haskell` reinstallable and keep it as the public
API for Template Haskell.
All of the wired-in identifiers are moved to `ghc-internal`.
This necessitates also moving much of `ghc-boot-th` into `ghc-internal`.
These modules are then re-exported from `ghc-boot-th` and
`template-haskell`.
To avoid a dependency on `template-haskell` from `lib:ghc`, we instead
depend on the TH ASTs via `ghc-boot-th`.

As `template-haskell` no longer has special status, we can drop the
logic adding an implicit dependency on `template-haskell` when using TH.
We can also drop the `template-haskell-next` package, which was
previously used when bootstrapping.

When bootstrapping, we need to vendor the TH AST modules from
`ghc-internal` into `ghc-boot-th`. This is controlled by the `bootstrap`
cabal flag as before. See Note [Bootstrapping Template Haskell].

We split out a GHC.Internal.TH.Lift module resolving #24752.
This module is only built when not bootstrapping.

Resolves #24703

GHC Testsuite Readme

For the full testsuite documentation, please see here.

Quick Guide

Commands to run testsuite:

  • Full testsuite: hadrian/build test
  • Using more threads: hadrian/build test -j12
  • Reduced (fast) testsuite: hadrian/build test --test-speed=fast
  • Run a specific test: hadrian/build test --only="tc055 tc054"
  • Test a specific 'way': hadrian/build test --test-way=optllvm
  • Skip performance tests: hadrian/build test --skip-perf
  • Set verbosity: hadrian/build test --test-verbose=<n> where n=0: No per-test output, n=1: Only failures, n=2: Progress output, n=3: Include commands called (default), n=4: Include perf test results unconditionally, n=5: Echo commands in subsidiary make invocations

Testsuite Ways

The testsuite can be run in a variety of 'ways'. This concept refers to different ways that GHC can compile the code. For example, using the native code generator (-fasm) is one way, while using the LLVM code generator (-fllvm) is another way.

The various ways that GHC supports are defined in config/ghc

Adding Tests
