[X86][LLVM]Expanding Supports lowerInterleavedStore() in X86InterleavedAccess (VF16 stride 4).

[m_zuckerman]

Summary

This patch expands the support of lowerInterleavedStore to 16x8i stride 4.

LLVM creates suboptimal shuffle code-gen for AVX2. In overall, this patch is a specific fix for the pattern (Strid=4 VF=16) and we plan to include more patterns in the future.

The patch goal is to optimize the following sequence:
At the end of the computation, we have ymm2, ymm0, ymm12 and ymm3 holding
each 16 chars:

c0, c1, , c16
m0, m1, , m16
y0, y1, , y16
k0, k1, ., k16

And these need to be transposed/interleaved and stored like so:

c0 m0 y0 k0 c1 m1 y1 k1 c2 m2 y2 k2 c3 m3 y3 k3 ....

Small modification on the function name

the comment is a bit misleading since it depends on whether we are loading or storing. can you expand the comment to state exactly what is supported?

126

you can use ShuffleElemSize

127

you can early exit at the beginning of the function on !Subtarget.hasAVX()

132

so this check isn't needed in the previous if?

Can you try to simplify this function? its getting overly complicated IMO.

366

maybe pass NumSubVecElems to interleave8bitStride4 and have it calculate the MVTs ?

Can you please compress this into one line? Otherwise, it looks good to me.

I would personally be fine with doing that in an NFC follow-up patch.

Otherwise, this LGTM.

LGTM with one minor comment.

you can use MVT::getVectorVT() directly, without creating the Type first.
