gitlab-ci: Disable darwin hadrian job

See #16771

We don't have enough capacity for the two jobs currently.

[skip ci] Improve the documentation of the CNF primops. In this context, the term "size" is ambiguous and is now avoided. Additionally, the distinction between a CNF and the blocks that comprise it has been emphasize. The vocabulary has been made more consistent with the vocabulary in the C source for CNF.

TmOracle: Replace negative term equalities by refutable PmAltCons

The `PmExprEq` business was a huge hack and was at the same time vastly
too powerful and not powerful enough to encode negative term equalities,
i.e. facts of the form "forall y. x ≁ Just y".

This patch introduces the concept of 'refutable shapes': What matters
for the pattern match checker is being able to encode knowledge of the
kind "x can no longer be the literal 5". We encode this knowledge in a
`PmRefutEnv`, mapping a set of newly introduced `PmAltCon`s (which are
just `PmLit`s at the moment) to each variable denoting above
inequalities.

So, say we have `x ≁ 42 ∈ refuts` in the term oracle context and
try to solve an equality like `x ~ 42`. The entry in the refutable
environment will immediately lead to a contradiction.

This machinery renders the whole `PmExprEq` and `ComplexEq` business
unnecessary, getting rid of a lot of (mostly dead) code.

See the Note [Refutable shapes] in TmOracle for a place to start.

Add HEAP_PROF_SAMPLE_END event to mark end of samples

This allows a user to observe how long a sampling period lasts so that
the time taken can be removed from the profiling output.

Fixes #16697

Fix #16700: Tiny errors in output of GHCi commands :forward and :info

`:info Coercible` now outputs the correct section number of the GHCi User's guide together with the secion title.

`:forward x` gives the correct syntax hint.

Factor out 'getLibDir' / 'getBaseDir' into a new GHC.BaseDir ghc-boot module

ghc-pkg and ghc already both needed this. I figure it is better to
deduplicate, especially seeing that changes to one (FreeBSD CPP) didn't
make it to the other.

Additionally in !1090 I make ghc-pkg look up the settings file, which
makes it use the top dir a bit more widely. If that lands, any
difference in the way they find the top dir would be more noticable.

That change also means sharing more code between ghc and ghc-package
(namely the settings file parsing code), so I'd think it better to get
off the slipperly slope of duplicating code now.

Preserve ShadowInfo when rewriting evidence

When the canonicaliser rewrites evidence of a Wanted, it
should preserve the ShadowInfo (ctev_nosh) field.  That is,
a WDerive should rewrite to WDerive, and WOnly to WOnly.

Previously we were unconditionally making a WDeriv, thereby
rewriting WOnly to WDeriv.  This bit Nick Frisby (issue #16735)
in the context of his plugin, but we don't have a compact test
case.

The fix is simple, but does involve a bit more plumbing,
to pass the old ShadowInfo around, to use when building
the new Wanted.

Fix isValidNatural: The BigNat in NatJ# must have at least 2 limbs

Previously the `integer-gmp` variant of `isValidNatural` would fail to
detect values `<= maxBound::Word` that were incorrectly encoded using
the `NatJ#` constructor.

Hadrian: use deb9 Docker images instead of deb8 for CI jobs

This should fix #16739, where we seem to be getting extra carets in
a test's output because of the gcc that ships with the deb8 image,
whule we're not observing those extra carets in the deb9-based (Make)
jobs.

gitlab-ci: Linters, don't allow to fail

Ben disabled them in cd85f8a71bb56cff332560e1d571b3406789fb71 but didn't
say how or why they were broken.

gitlab-ci: Use --unshallow when fetching for linters

GitLab creates a shallow clone. However, this means that we may not have
the base commit of an MR when linting, causing `git merge-base` to fail.
Fix this by passing `--unshallow` to `git fetch`, ensuring that we have
the entire history.

Maintain separate flags for C++ compiler invocations

Previously we would pass flags intended for the C compiler to the C++
compiler (see #16738). This would cause, for instance, `-std=gnu99` to
be passed to the C++ compiler, causing spurious test failures. Fix this
by maintaining a separate set of flags for C++ compilation invocations.
