Add JS backend adapted from the GHCJS project by Luite Stegeman.

Some features haven't been ported or implemented yet. Tests for these
features have been disabled with an associated gitlab ticket.

- Remove unused functions exprToCoercion_maybe, applyTypeToArg,
  typeMonoPrimRep_maybe, runtimeRepMonoPrimRep_maybe.
- Replace orValid with a simpler check
- Use splitAtList in applyTysX
- Remove calls to extra_clean in the testsuite; it does not do anything.

Metric Decrease:

GHC produced broken executables with rebindable if and -fhpc if `ifThenElse` expected non-Bool condition until GHC 9.0. This adds a simple regression test.

Test T2632 is a stage1 test that failed because of the Q => Quote change.

The remaining tests did not use quotation and failed when the path
contained a space.

* Make sure files are being read/written in UTF-8. Set encoding while writing
  HTML output. Also set encoding while writing and reading .tix files although
  we don't yet have a ticket complaining that this poses problems.
* Set encoding in html header to utf8
* Upgrade to new version of 'hpc' library and reuse `readFileUtf8`
  and `writeFileUtf8` functions
* Update git submodule for `hpc`
* Bump up `hpc` executable version

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

This reverts commit 76c8fd67.

* Add a new flag, `-fignore-optim-changes`, allowing them to avoid
  recompilation if the only changes are to the `-O` level or to
  flags controlling optimizations.

* When `-fignore-optim-changes` is *off*, recompile when optimization
  flags (e.g., `-fno-full-laziness`) change. Previously, we ignored
  these unconditionally when deciding whether to recompile a module.

The script I used is included as testsuite/driver/kill_extra_files.py,
though at this point it is for mostly historical interest.

Some of the tests in libraries/hpc relied on extra_files.py, so this
commit includes an update to that submodule.

One test in libraries/process also relies on extra_files.py, but we
cannot update that submodule so easily, so for now we special-case it
in the test driver.

The problem with ignore_output is that it hides errors for WAY=ghci.
GHCi always returns with exit code 0 (unless it is broken itself).

For example: ghci015 must have been failing with compile errors for
years, but we didn't notice because all output was ignored.

Therefore, replace all uses of ignore_output with either ignore_stderr
or ignore_stdout. In some cases I opted for adding the expected output.

Update submodule hpc and stm.

* Set config settings directly in mk/test.mk, instead of indirectly in
  config/ghc
* passing --hpcdir for WAY=hpc is unnecessary

No point in pretending other compilers can use the GHC testsuite. This
makes the *.T files a bit shorter.

Summary:
BAD: "." ++ "/" ++ "/absolute/path" == ".//absolute/path"
GOOD: "." </> "/absolute/path" == "/absolute path"

Also replace `++ ".ext"` with `<.> "ext"`. Although it doesn't fix any
bugs in this instance, it might in some other. As a general rule it's
better not to use (++) on FilePaths.
