[X86][SSE] Add MULHS/MULHU custom lowering for i8 vectors

[RKSimon]

Summary

Currently this is to mainly to prevent scalarization of integer division by constants.

Right now, Subtarget.hasInt256() should be true for 256 bit vector, since we add the custom lowering for those only when this predicate is true.
I.e., this is dead code at the moment, right?

19078

This returns the low value, right?
I believe we miss a shift before the truncate.

19094

A few comments on how we achieve the extraction wouldn’t hurt :).

E.g., Fill the 8 high bits of a v8i16 vector with the low input vector.
Shift that vector right by 8, to put the 8 relevant bits at the right place and fill the 8 high bits with 0 or sign extension.

[RKSimon]

Revised based on Quentin's feedback.

Enabled v32i8 and v16i16 MULHS/MULHU custom lowering on AVX1 targets to prevent scalarization - I can commit the v16i16 support separately if necessary.

Improved the AVX 32i8 lowerings to make use ymm PACKUS (saves 2cy on my Carrizo tests) and added a missing shift to the v16i8 version (I had stupidly only locally tested 32i8 on AVX2 hardware).

Tried to improve comments on what is going on.

Hi Simon,

LGTM. Couple of nits inlined.

Cheers,

Add that unlike the smaller PACKUS, the ymm variant interleaves the 128 bits of the both sources.
Without that in mind, the shuffle does not make sense, whereas it is definitely required :).
