[X86][SSE] Generalised CMP+AND1 combine to ZERO/ALLBITS+MASK
Patch to generalize combinePCMPAnd1 (for handling SETCC + ZEXT cases) to work for any input that has zero/all bits set masked with an 'all low bits' mask.
Replaced the implicit assumption of shift availability with a call to SupportedVectorShiftWithImm.
Part 1 of 3.
