[SystemZ] Bugfix in SystemZVectorConstantInfo

In order to correctly load an all-ones FP NaN value into a floating point
register with a VGBM, the analyzed 32/64 FP bits must first be shifted left
(into element 0 of the vector register).

SystemZVectorConstantInfo has so far relied on element replication which has
bypassed the need to do this shift, but now it is clear that this must be
done in order to handle NaNs.

[InstCombine] visitCallInst - retain undefs in vector funnel shift amounts

By always performing a modulo on the shift amount constants this was causing undef amounts being replaced with zero, meaning we were losing funnel shift by splat (with undef) patterns.

Tweaked the shift amount bounds check to support (passthrough) undefs, and use Constant::mergeUndefsWith to preserve the undefs after folding.

[mlir] expand the legal floating-point types in the LLVM IR dialect type check

This patch adds a couple missing LLVM IR dialect floating point types to
the legality check.

[libc++] Remove signal-based checkpoints in libc++ tests

While this adds some convenience to the test suite, it prevents the tests
using these checkpoints from being used on systems where signals are not
available, such as some embedded systems. It will also prevent these tests
from being constexpr-friendly once e.g. std::map is made constexpr, due
to the use of statics.

Instead, one can always use a debugger to figure out exactly where a
test is failing when that isn't clear from the log output without

[flang] Rework host runtime folding and enable REAL(2) folding with it.

- Rework the host runtime table so that it is constexpr to avoid
  having to construct it and to store/propagate it.
- Make the interface simpler (remove many templates and a file)
- Enable 16bits float folding using 32bits float host runtime
- Move StaticMultimapView into its own header to use it for host

[profile] Remove useless msync when dumping gcda files

According the mmap man page ( is only required to precisely control updates, so we can safely remove it.
Since gcda files are dumped just before to call exec** functions, dump need to be fast.
On my computer, Firefox built with --coverage needs ~1min40 to display something and in removing msync it needs ~8s.
