Dehao Chen 0faf9ed31e Add LiveRangeShrink pass to shrink live range within BB. ...

Summary: LiveRangeShrink pass moves instruction right after the definition with the same BB if the instruction and its operands all have more than one use. This pass is inexpensive and guarantees optimal live-range within BB.
