[x86] scalarize extract element 0 of FP math

[spatel]

Summary

This is another step towards ensuring that we produce the optimal code for reductions, but there are other potential benefits as seen in the tests diffs:

1. Memory loads may get scalarized resulting in more efficient code.
2. Memory stores may get scalarized resulting in more efficient code.
3. Complex ops like fdiv/sqrt get scalarized which may be faster instructions depending on uarch.
4. Even simple ops like addss/subss/mulss/roundss may result in faster operation/less frequency throttling when scalarized depending on uarch.

The TODO comment suggests 1 or more follow-ups for opcodes that can currently result in regressions.
The tests for "minimum" and "maximum" IR in extractelement-fp.ll are commented out because those currently crash independently of this patch. I'm not sure what that problem is yet.

llvm_unreachable

[spatel]

Patch updated:
Add llvm_unreachable so we don't accidentally return without a value.

(style) Is clang-format happy with this?

Should unary ops handle non-zero index extractions?

Definitely not. :)
I was trying to keep the list organized and save space while fetching things from the header file, but that didn't last. I'll fix it to use the standard 1-case-per-line.

llvm/test/CodeGen/X86/extractelement-fp.ll

138

There's some set of conditions under which we want to do that, but I don't think unary alone is it. For example, it probably makes sense to shuffle an fdiv to avoid the vector op. Also, anything that would get expanded via unrolling during legalization? I'll add a TODO note so we can follow-up.

[spatel]

Patch updated:

1. Added TODO comment about handling non-zero extract index.
2. Reformatted switch.

[spatel]

Ping.

LGTM with a couple of minors

You should be able to add RSQRTSS + RCPSS as well?

Slightly annoying - the vector version broadcasts a scalar, the scalar version loads a whole vector..... Can you raise a bug on this please?

[spatel]

llvm/lib/Target/X86/X86ISelLowering.cpp

Yes - I'll add that to the TODO. There are other x86-specific opcodes like FMAX/FMAXC too, so I need to do a full audit.
