[PATCH] D32563: Add LiveRangeShrink pass to shrink live range within BB.

patch to move the pass to x86 is proposed: https://reviews.llvm.org/D33294

Will have a separate patch to fix the REG_SEQUENCE handling once I get a test that I can include in unittesting. I suppose the fix is: ignore instruction whose def register size is no less than the sum of the use register sizes?

Thanks,
Dehao
