When we split above an instruction (for example because of splintering), we may introduce moves that are redundant in the context of moves on subsequent instructions. Currently, we only detect such redundancies by allowing moves to skip over Nop instructions (true nops, with no input/output). We can also skip over other cases, for example over constant definitions (nop with an output), since whatever moves happen above it do not influence the instruction's outcome. We may be able to handle other cases, too - in subsequent CLs. BUG= Review URL: https://codereview.chromium.org/1422333003 Cr-Commit-Position: refs/heads/master@{#31662}
