X86CallFrameOptimization: Recognize 'store 0/-1 using and/or' idioms

X86CallFrameOptimization: Recognize 'store 0/-1 using and/or' idioms

Summary:
r264440 added or/and patterns for storing -1 or 0 with the intention of decreasing code size. However,
X86CallFrameOptimization does not recognize these memory accesses so it will not replace them with push's when profitable.

This patch fixes this problem by teaching X86CallFrameOptimization these store 0/-1 idioms.

An alternative fix would be to prevent the 'store 0/1 idioms' patterns from firing when accessing the stack. This would save
the need to teach the pass about these idioms. However, because X86CallFrameOptimization does not always fire we may result
in cases where neither X86CallFrameOptimization not the patterns for 'store 0/1 idioms' fire.

Fixes pr34863
