Refactor the rules for .hi and .o into a single rule using `&%>` #16764

Currently the rule for .hi files just triggers (via need) the rule
for the .o file, and .o rule generates both the .o and .hi file.
Likewise for .o-boot and .hi-boot files. This is a bit of an abuse
of Shake, and in fact shake supports rules with multiple output
with the &%> function. This exact use case appears in Neil
Mitchell's paper *Shake Before Building* section 6.3.

testsuite: Fix and extend closure_size test

This was previously broken in several ways. This is fixed and it also
now tests arrays. Unfortunately I was unable to find a way to continue
testing PAP and FUN sizes; these simply depend too much upon the
behavior of the simplifier.

I also tried to extend this to test non-empty arrays as well but
unfortunately this was non-trivial as the array card size constant isn't
readily available from haskell.

Fixes #16531.

ghc-heap: Add closure_size_noopt test

Refine the GHCI macro into HAVE[_{INTERNAL, EXTERNAL}]_INTERPRETER

As discussed in #16331, the GHCI macro, defined through 'ghci' flags
in ghc.cabal.in, ghc-bin.cabal.in and ghci.cabal.in, is supposed to indicate
whether GHC is built with support for an internal interpreter, that runs in
the same process. It is however overloaded in a few places to mean
"there is an interpreter available", regardless of whether it's an internal
or external interpreter.

For the sake of clarity and with the hope of more easily being able to
build stage 1 GHCs with external interpreter support, this patch splits
the previous GHCI macro into 3 different ones:

- HAVE_INTERNAL_INTERPRETER: GHC is built with an internal interpreter
- HAVE_EXTERNAL_INTERPRETER: GHC is built with support for external interpreters
- HAVE_INTERPRETER: HAVE_INTERNAL_INTERPRETER || HAVE_EXTERNAL_INTERPRETER

Make `haddock_testsuite` respect `--test-accept`

Suppose you've made changes that affect the output of `haddockHtmlTest`
so that the following is failing:

    ./hadrian/build.sh -c --only=haddockHtmlTest test

Then, the following will accept new output for Haddock's test cases.

    ./hadrian/build.sh -c --only=haddockHtmlTest test --test-accept

You still do need to make sure those new changes (which show up in
Haddock's tree) get committed though.

Fixes #16694

Hadrian: teach the RTS that PROFILING implies TRACING

As discussed in #16744, both the Make and Hadrian build systems
have special code to always pass -eventlog whenever -prof or -debug
are passed. However, there is some similar logic in the RTS itself only
for defining TRACING when the DEBUG macro is defined, but no such logic
is implemented to define TRACING when the PROFILING macro is defined.
This patch adds such a logic and therefore fixes #16744.

testsuite/mk/boilerplate.mk: rename 'ghc-config-mk' to 'ghc_config_mk'

Make/shell variable names which contain dashes can cause problems under
some conditions. The 'ghc-config-mk' variable from testsuite/mk/boilerplate.mk
that I made overridable (by Hadrian) in ba0aed2e was working as expected when
our Hadrian/Linux job was based off the deb8 Docker image, but broke when
I switched the job to use our deb9-based image, in 3d97bad6. The exact
circumstances/tool versions that trigger this problem are unknown, but
changing the variable's name to 'ghc_config_mk' lets us work around the issue.

This fixes the annth_compunits and annth_make test failures that showed up
when we switched the Hadrian/Linux job to use the deb9 environment.

Fix #16525: ObjectCode freed wrongly because of lack of info header check

`checkUnload` currently doesn't check the info header of static objects.
Thus, it may free an `ObjectCode` struct wrongly even if there's still a
live static object whose info header lies in a mapped section of that
`ObjectCode`. This fixes the issue by adding an appropriate check.

PrelRules: Ensure that string unpack/append rule fires with source notes

Previously the presence of source notes could hide nested applications
of `unpackFoldrCString#` from our constant folding logic. For instance,
consider the expression:

```haskell
unpackFoldrCString# "foo" c (unpackFoldrCString# "baz" c n)
```

Specifically, ticks appearing in two places can defeat the rule:

  a. Surrounding the inner application of `unpackFoldrCString#`
  b. Surrounding the fold function, `c`

The latter caused the `str_rules` testcase to fail when `base` was built
with `-g3`.

Fixes #16740.

Add `PmNCons` to `Check` for correct warnings in the presence of `COMPLETE` groups

Previously, we had an elaborate mechanism for selecting the warnings to
generate in the presence of different `COMPLETE` matching groups that,
albeit finely-tuned, produced wrong results from an end user's
perspective in some cases (#13363).

The underlying issue is that at the point where the `ConVar` case has to
commit to a particular `COMPLETE` group, there's not enough information
to do so and the status quo was to just enumerate all possible complete
sets nondeterministically.
The `getResult` function would then pick the outcome according to
metrics defined in accordance to the user's guide. But crucially, it
lacked knowledge about the order in which affected clauses appear,
leading to the surprising behavior in #13363.

The introduction of an `PmNCons` variant in `PmPat` fixes this: Instead
of committing to a particular `COMPLETE` group in the `ConVar` case,
we now split off the matching constructor incrementally and record the
newly covered case in `PmNCons`.
After all clauses have been processed this way, we filter out any value
vector abstractions from the uncovered set involving `PmNCons` whose set
of covered constructors completely overlap a `COMPLETE` set.
