Some of these are marked with FIXME, as there is bug in lowering
e.g. _mm512_mask_cmp_ps_mask.

This is an early step towards matching Instructions by attributes other than the opcode. This will be necessary for cast/call alternates which share the same opcode but have different types/intrinsicIDs etc. - which we could vectorize as long as we split them using the alternate mechanism.

I think code is dead, because the only way to see
Path as empty seems would be if replaceThinLTOSuffix()
replaced some prefix with empty prefix (making the result
Path empty).
But it is impossible to pass the empty prefix,
we would file in driver:
https://github.com/llvm-mirror/lld/blob/master/ELF/Driver.cpp#L669

that has required alignment. This avoids issues that keep coming up with
function pointers being less aligned.
I'm pretty annoyed that we can't take advantage of function alignment
even on platforms where they *are* aligned, but build modes and other
things make taking advantage of it somewhere between hard and
impossible. The best case scenario would still embed various build modes
into the ABI causing really hard to debug issues if you compiled one
object file differently from another. =/
This should at least bring the bots back that were having trouble with
this.

Summary:
Currently, anonymous types are merged into the same redecl chain even if they
are structurally inequivalent. This results that global objects are not
imported, if there are at least two global objects with different anonymous
types. This patch provides a fix.

Similar to PR/25526, fast-regalloc introduces spills at the end of basic
blocks. When this occurs in between an ll and sc, the stores can cause the
atomic sequence to fail.
This patch fixes the issue by introducing more pseudos to represent atomic
operations and moving their lowering to after the expansion of postRA
pseudos.
This version addresses issues with the initial implementation and covers
all atomic operations.
This resolves PR/32020.
Thanks to James Cowgill for reporting the issue!

The flag "--no-as-needed" is not recognized by the linker on macOS making the following tests fail:
ompt/loadtool/tool_available/tool_available.c
ompt/loadtool/tool_not_available/tool_not_available.c
This patch removes this flag for macOS and adds it only for Linux and Windows.
I tested it on Ubuntu 16.04 and macOS HighSierra, with Clang/LLVM 6.0.1 and OpenMP trunk.
This solution was also discussed in the OpenMP-dev mailing list.

This patch also adds instructions for predicated FP square-root and
reciprocal exponent.
The added instructions are:
- FRINTI Round to integral value (current FPCR rounding mode)
- FRINTX Round to integral value (current FPCR rounding mode, signalling inexact)
- FRINTA Round to integral value (to nearest, with ties away from zero)
- FRINTN Round to integral value (to nearest, with ties to even)
- FRINTZ Round to integral value (toward zero)
- FRINTM Round to integral value (toward minus Infinity)
- FRINTP Round to integral value (toward plus Infinity)
- FSQRT Floating-point square root
- FRECPX Floating-point reciprocal exponent

Previously we could only negate the FMADD opcodes. This used to be mostly ok when we lowered FMA intrinsics during lowering. But with the move to llvm.fma from target specific intrinsics, we can combine (fneg (fma)) to (fmsub) earlier. So if we start with (fneg (fma (fneg))) we would get stuck at (fmsub (fneg)).
This patch fixes that so we can also combine things like (fmsub (fneg)).
