[PATCH] D146810: [CodeGen] Compile-time improvement for Machine Late Instructions Cleanup Pass.

Thanks for trying the idea of a single map!

On SystemZ, the two versions show practically identical runtimes, so there is no winner. Is there any difference at all on your machine?

I am thinking maybe it would be possible to lookup Reg only once by calling removeRedundantDef() with MI and also the KillMI. That way, clearKillsForDef() wouldn't have to duplicate the same lookup.
