TestRunner: Added --chart to display a chart of performance tests
This uses the Chart.js javascript library.
Everything is put into a standalone .html file and opened with the
default browser.
I also simplified the text output to use the same data as the chart.
You can now use a commit range with git's ".." syntax.
The --ci option will use results from CI (you'll need to fetch them
first):
$ git fetch https://gitlab.haskell.org/ghc/ghc-performance-notes.git refs/notes/perf:refs/notes/ci/perf
$ python3 testsuite/driver/perf_notes.py --ci --chart --test-env x86_64-darwin --test-name T9630 master~500..master

Use a better strategy for determining the offset applied to foreign function arguments that have an unlifted boxed type. We used to use the type of the argument. We now use the type of the foreign function. Add a test to confirm that the roundtrip conversion between an unlifted boxed type and Any is sound in the presence of a foreign function call.

Hadrian: fix OSX build failure and add an OSX/Hadrian CI job
The OSX build failure introduced in 3aa71a22 was due to a change in the
glob we use to collect libffi shared libraries in hadrian/src/Rules/Libffi.hs.
This commit fixes the problem and adds an OSX CI job that builds GHC with
Hadrian, to make sure we don't break it again.

Add GHCi :instances command
This commit adds the `:instances` command to ghci following proosal
number 41.
This makes it possible to query which instances are available to a given
type.
The output of this command is all the possible instances with type
variables and constraints instantiated.

[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.

`: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.

Hadrian: use deb9 Docker images instead of deb8 for CI jobs
This should fix #16739, where we seem to be getting extra carets in

whule we're not observing those extra carets in the deb9-based (Make)
jobs.

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.

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: 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`

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.

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

abort everything even though the stack might still have elements left to
process.

PrelRules: Don't break let/app invariant in shiftRule
Previously shiftRule would rewrite as invalid shift like
```
let x = I# (uncheckedIShiftL# n 80)
in ...
```
to
```
let x = I# (error "invalid shift")
in ...
```
However, this breaks the let/app invariant as `error` is not
okay-for-speculation. There isn't an easy way to avoid this so let's not
try. Instead we just take advantage of the undefined nature of invalid
shifts and return zero.
