Auto merge of #36388 - pcwalton:copy-propagation, r=nikomatsakis
librustc_mir: Implement def-use chains and trivial copy propagation on MIR. This only supports trivial cases in which there is exactly one def and one use. Currently, some random unrelated MIR tests are failing, probably just because they haven't been updated. r? @eddyb
