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 ....
