[PATCH] D37141: [x86] Flesh out the custom ISel for RMW aritmetic ops with used flags to cover the bitwise operators.

Nothing really exciting here, this just stamps out the rest of the core
operations that can RMW memory and set flags.

Still not implemented here: ADC, SBB. Those will require more
interesting logic to channel the flags *in*.

Depends on https://reviews.llvm.org/D37139.
