Simon Pilgrim d4f7cbfea6 [X86][AVX] Start shuffle combining from ZERO_EXTEND_VECTOR_INREG (PR40685) ...

Just enable this for AVX for now as SSE41 introduces extra register moves for the PMOVZX(PSHUFD(V)) -> UNPCKH(V,0) pattern (but otherwise helps reduce port5 usage on Intel targets).

Only AVX support is required for PR40685 as the issue is due to 8i8->8i32 zext shuffle leftovers.
