Sanjay Patel aab686b3f7 [x86] enable CGP memcmp() expansion for 2/4/8 byte sizes ...

There are a couple of potential improvements as seen in the IR and asm:
1. We're unnecessarily extending to a larger type to compare values.
2. The codegen for (select cond, 1, -1) could avoid a cmov.
(or we could change the order of the compares, so we have a select with 0 operand)
