[X86] Add v32i8 shuffle lowering strategy to recognize two v4i64 vectors truncated to v4i8 and concatenated into the lower 8 bytes with undef/zero upper bytes.
This patch recognizes the shuffle pattern we get from a
v8i64->v8i8 truncate when v8i64 isn't a legal type.
With VLX we can use two VTRUNCs, unpckldq, and a insert_subvector.
