[X86] Teach LowerMUL/LowerMULH for vXi8 to unpack constant RHS.

[craig.topper]

Summary

We need to unpackl and unpackh the operands to use two vXi16 multiplies. Previously it looks like the low unpack would get constant folded at least in the 128-bit case after shuffle lowering turned the unpackl into ZERO_EXTEND_VECTOR_INREG and X86 custom DAG combined it. The same doesn't happen for the high half. So we'd load a constant and then shuffle it. But the low half would just be loaded and used by the multiply directly.

After this patch we now end up with a constant pool entry for the low and high unpacks separately with no shuffle operations.

This is a step towards removing custom constant folding for ZERO_EXTEND_VECTOR_INREG/SIGN_EXTEND_VECTOR_INREG in the X86 backend.

Rebase and do the same in LowerMULH
