Previously `makefile_test` and `run_command` tests could easily end up
in a situation where they wouldn't be run if the user used the
`only_ways` modifier. The reason is to build the set of a ways to run
the test in we first start with a candidate set determined by the test
type (e.g. `makefile_test`, `compile_run`, etc.) and then filter that
set with the constraints given by the test's modifiers.
`makefile_test` and `run_command` tests' candidate sets were simply
`{normal}`, and consequently most uses of `only_ways` would result in
the test being never run.
To avoid this we rather use all ways as the candidate sets for these
test types. This may result in a few more testcases than we would like
(given that some `run_command` tests are insensitive to way) but this
can be fixed by adding modifiers and we would much rather run too many
tests than too few.
This fixes #16042 and a number of other tests afflicted by the same issue.
However, there were a few cases that required special attention:
* `T14028` is currently failing and is therefore marked as broken due
to #17300
* `T-signals-child` is fragile in the `threaded1` and `threaded2` ways
(tracked in #17307)

This moves all URL references to Trac tickets to their corresponding
GitLab counterparts.

|

|

This eliminates most uses of run_command in the testsuite in favor of the more
structured makefile_test.

The `clean_cmd` and `extra_clean` setup functions don't do anything.
Remove them from .T files.
Created using https://github.com/thomie/refactor-ghc-testsuite. This
diff is a test for the .T-file parser/processor/pretty-printer in that
repository.
find . -name '*.T' -exec ~/refactor-ghc-testsuite/Main "{}" \;
Tests containing inline comments or multiline strings are not modified.
Preparation for #12223.

These tests no longer compile, because the hmatrix api has completely
changed. Even if we managed to fix the tests, I don't think they would
provided much value, since the ghc/llvm bug from #5054 was not
reproducible in the first place.

Commit 673efccb3b uncovered a bug in LLVM code generation that produced
LLVM code that the LLVM compiler refused to compile:
{
clpH:
br label %clpH
}
This may well be a bug in LLVM itself. The solution is to keep the
existing entry label and rewrite the function as:
{
clpH:
br label %nPV
nPV:
br label %nPV
}
Thanks to Ben Gamari for pointing me in the right direction on this
one.

Summary:
Alignment needs to be a compile-time constant. Previously the code
generators had to jump through hoops to ensure this was the case as the
alignment was passed as a CmmExpr in the arguments list. Now we take
care of this up front.
This fixes #8131.

Summary:
This allows to link objects produced with the llvm code generator to be linked with -dead_strip. This applies to at least the iOS cross compiler and OS X compiler.

Test Plan: Create a ffi library and link it with -dead_strip. If the resulting binary does not crash, the patch works as advertised.

This is done as a separate `integer-gmp2` backend library because it
turned out to become a complete rewrite from scratch.
Due to the different (over)allocation scheme and potentially different
accounting (via the new `{shrink,resize}MutableByteArray#` primitives),
some of the nofib benchmarks actually results in increased allocation
numbers (but not necessarily an increase in runtime!). I believe the
allocation numbers could improve if `{resize,shrink}MutableByteArray#`
could be optimised to reallocate in-place more efficiently.
Here are the more apparent changes in the latest nofib comparision
between `integer-gmp` and `integer-gmp2`:

By default, `INTEGER_LIBRARY=integer-gmp2` is active now, which results
in the package `integer-gmp-1.0.0.0` being registered in the package db.
The previous `integer-gmp-0.5.1.0` can be restored by setting
`INTEGER_LIBRARY=integer-gmp` (but will probably be removed altogether
for GHC 7.12). In-tree GMP support has been stolen from the old
`integer-gmp` (while unpatching the custom memory-allocators, as well as
forcing `-fPIC`)
A minor hack to `ghc-cabal` was necessary in order to support two different
`integer-gmp` packages (in different folders) with the same package key.
There will be a couple of follow-up commits re-implementing some features
that were dropped to keep D82 minimal, as well as further
clean-ups/improvements.

This allows them to give framework failures.
I also had to change how setTestOpts works. Now, rather than applying
the options to the directory's "default options", it just stores the
options to be applied for each test (i.e. once we know the test name).
