[PowerPC] Split tests for constrained intrinsics

The test CodeGen/PowerPC/vector-constrained-fp-intrinsics.ll checks code
generation for constrained floating point intrinsics. Many test cases in
it were implemented using operations on constants. Constant folding of
constrained intrinsics would make these test cases almost useless,
because they would check only constant loading.

To keep the tests useful, operations on constants were replaced with
operations on function parameters.

[libcxx] [test] Fix the _supportsVerify check on Windows by fixing quoting

The pipes.quote function quotes using single quotes, the same goes
for the newer shlex.quote (which is the preferred form in Python 3).
This isn't suitable for quoting in command lines on Windows (and the
documentation for shlex.quote even says it's only usable for Unix

In general, the python subprocess.list2cmdline function should do
proper quoting for the platform's current shell. However, it doesn't
quote the ';' char, which we pass within some arguments to
Therefore use the custom reimplementation from lit.TestRunner which
is amended to quote ';' too.

The fact that arguemnts were quoted with single quotes didn't matter
for command lines that were executed by either bash or the lit internal
shell, but if executing things directly using, as in
_supportsVerify, the quoted path to %{cxx} fails to be resolved by the
Windows shell.

This unlocks 114 tests that previously were skipped on Windows.

[X86] Split FeatureFastVariableShuffle tuning into Lane-Crossing and Per-Lane variants

Currently, X86 backend only has a global one-size-fits-all `FeatureFastVariableShuffle` feature,
which controls profitability of both the cross-lane and per-lane variable shuffles.
I guess, this has been fine so far.

But at least on AMD Zen 3, while per-line variable shuffles (e.g. `VPSHUFB`)
are as fast as as shuffles with fixed/immediate mask,
while lane-crossing shuffles, e.g. `VPERMPS` is performing worse.

So to get the benefits of variable-mask shuffles, but not the drawbacks of lane-crossing shuffles,
as suggested by @RKSimon, split the feature flag into two.
