gitlab-ci: Disable shallow clones

Previously we were passing `--unshallow` to `git fetch` in the linting
rules to ensure that the base commit which we were linting with respect
to was available. However, this breaks due to GitLab's re-use of
working directories since `git fetch --unshallow` fails on a repository
which is not currently shallow.

Given that `git fetch --unshallow` circumvents the efficiencies provided
by shallow clones anyways, let's just disable them entirely.

There is no documented way to do disable shallow clones but on checking
the GitLab implementation it seems that setting `GIT_DEPTH=0` should do
the trick.

gitlab-ci: Fix submodule linting of commits

There is no notion of a base commit when we aren't checking a merge
request. Just check the HEAD commit.

gitlab-ci: Ensure that all commits on a branch are submodule-linted

The previous commit reworked things such that the submodule linter would
only run on the head commit. However, the linter only checks the
submodules which are touched by the commits it is asked to lint.
Consequently it would be possible for a bad submodule to sneak through.

Thankfully, we can use the handy CI_COMMIT_BEFORE_SHA attribute to
find the base commit of the push.

hadrian: Properly partition options in sourceArgs

Previously if you build the `ghc` package then it would has the default
opts and the library opts. This is different behaviour to make where the
library opts are only reserved for things in the `libraries`
subdirectory (I believe)

Fixes #16716

Handle trailing path separator in package DB names (#16360)

Package DB directories with trailing separator (provided via
GHC_PACKAGE_PATH or via -package-db) resulted in incorrect calculation of
${pkgroot} substitution variable.  Keep the trailing separator while
resolving as directory or file, but remove it before dropping the last
path component with takeDirectory.

Closes #16360.

Fix #16517 by bumping the TcLevel for method sigs

There were actually two bugs fixed here:

1. candidateQTyVarsOfType needs to be careful that it does not
   try to zap metavariables from an outer scope as "naughty"
   quantification candidates. This commit adds a simple check
   to avoid doing so.

2. We weren't bumping the TcLevel in kcHsKindSig, which was used
   only for class method sigs. This mistake led to the acceptance
   of

     class C a where
       meth :: forall k. Proxy (a :: k) -> ()

   Note that k is *locally* quantified. This patch fixes the
   problem by using tcClassSigType, which correctly bumps the
   level. It's a bit inefficient because tcClassSigType does other
   work, too, but it would be tedious to repeat much of the code
   there with only a few changes. This version works well and is
   simple.

And, while updating comments, etc., I noticed that tcRnType was
missing a pushTcLevel, leading to #16767, which this patch also
fixes, by bumping the level. In the refactoring here, I also
use solveEqualities. This initially failed ghci/scripts/T15415,
but that was fixed by teaching solveEqualities to respect
-XPartialTypeSignatures.

This patch also cleans up some Notes around error generation that
came up in conversation.

Test case: typecheck/should_fail/T16517, ghci/scripts/T16767

Add disable/enable commands to ghci debugger #2215

This patch adds two new commands `:enable` and `:disable` to the GHCi debugger.
Opposite to `:set stop <n> :continue` a breakpoint disabled with `:disable` will
not loose its previously set stop command.
A new field breakEnabled is added to the BreakLocation data structure to
track the enable/disable state. When a breakpoint is disabled with a `:disable`
command, the following happens:

The corresponding BreakLocation data element is searched dictionary of the
`breaks` field of the GHCiStateMonad. If the break point is found and not
already in the disabled state, the breakpoint is removed from bytecode.
The BreakLocation data structure is kept in the breaks list and the new
breakEnabled field is set to false.

The `:enable` command works similar.

The breaks field in the GHCiStateMonad was changed from an association list
to int `IntMap`.

Remove CPP ensuring word size is 32 or 64 bits around Addr# <-> int# primops

It shouldn't be needed these days, and those primops are "highly
deprecated" anyways.

This fits with my plans because it removes one bit of target-dependence
of the builtin primops, and this is the hardest part of GHC to make
multi-target.

rts: Fix RetainerProfile early return with TREC_CHUNK

When pop() returns with `*c == NULL` retainerProfile will immediately
return. All other code paths is pop() continue with the next stackElement
when this happens so it seems weird to me that TREC_CHUNK we would suddenly
abort everything even though the stack might still have elements left to
process.

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.

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.

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.
