[X86] Call lowerShuffleAsBitMask for 512-bit vectors in lowerShuffleAsBlend.

[craig.topper]

Summary

This patch enables the use of lowerShuffleAsBitMask for 512-bit blends before
falling back to move immedate, GPR to k-register, and masked op.

I had to make some changes to support v8i64 when i64 is not a legal type. And to
support floating point types.

This trades a load for the move immediate and GPR move which is higher latency.
But its probably better for register pressure not having to hop through other
register classes. The load+and should play better with LICM and
rematerialization I think.

[RKSimon]

Should we not do this if opt-size is set?

[craig.topper]

Add optsize qualification. Copied one of the test cases in avx512-mask-op.ll and add the optsize attribute to test.

[RKSimon]

LGTM - cheers

I've bisected https://bugs.llvm.org/show_bug.cgi?id=41203 to this commit, which seems to cause crashes when building the test-suite with AXV512.
