cmm/Parser: Atomic load syntax

Originally I had thought I would just use the `prim` call syntax instead
of introducing new syntax for atomic loads. However, it turns out that
`prim` call syntax tends to make things quite unreadable. This new
syntax seems quite natural.

codeGen: Introduce ThreadSanitizer instrumentation

This introduces a new Cmm pass which instruments the program with
ThreadSanitizer annotations, allowing full tracking of mutator memory
accesses via TSAN.

Hadrian: Drop TSAN_ENABLED define from flavour

This is redundant since the TSANUtils.h already defines it.

rts: Ensure that global regs are never passed as fun call args

This is in general unsafe as they may be clobbered if they are mapped to
caller-saved machine registers. See Note [Register parameter passing].

Package Imports: Get candidate packages also from re-exported modules

Previously we were just looking at the direct imports to try and work
out what a package qualifier could apply to but #22333 pointed out we
also needed to look for reexported modules.

Fixes #22333

compiler: Ensure that MutVar operations have necessary barriers

Here we add acquire and release barriers in readMutVar# and
writeMutVar#, which are necessary for soundness.

Fixes #22468.

Fix bogus test in Lint

The Lint check for branch compatiblity within an axiom, in
GHC.Core.Lint.compatible_branches was subtly different to the
check made when contructing an axiom, in
GHC.Core.FamInstEnv.compatibleBranches.

The latter is correct, so I killed the former and am now using the
latter.

On the way I did some improvements to pretty-printing and documentation.

checkValidInst: Don't expand synonyms when splitting sigma types

Previously, the `checkValidInst` function (used when checking that an instance
declaration is headed by an actual type class, not a type synonym) was using
`tcSplitSigmaTy` to split apart the `forall`s and instance context. This is
incorrect, however, as `tcSplitSigmaTy` expands type synonyms, which can cause
instances headed by quantified constraint type synonyms to be accepted
erroneously.

This patch introduces `splitInstTyForValidity`, a variant of `tcSplitSigmaTy`
specialized for validity checking that does _not_ expand type synonyms, and
uses it in `checkValidInst`.

Fixes #22570.

compiler: Add -f[no-]split-sections flags

Here we add a `-fsplit-sections` flag which may some day replace
`-split-sections`. This has the advantage of automatically providing a
`-fno-split-sections` flag, which is useful for our packaging because we
enable `-split-sections` by default but want to disable it in certain
configurations.

hadrian: Add no_split_sections tranformer

This transformer reverts the effect of `split_sections`, which we intend
to use for platforms which don't support split sections.

as "werror".

packaging: Build perf builds with -split-sections

In 8f71d958 the make build system was made to use split-sections on
linux systems but it appears this logic never made it to hadrian.
There is the split_sections flavour transformer but this doesn't appear
to be used for perf builds on linux.

This is disbled on deb9 and windows due to #21670

Closes #21135
