Auto merge of #77373 - jonas-schievink:rm-rf-copy-prop, r=oli-obk
Remove the old copy propagation pass This pass was added a long time ago, and has not really seen much improvement since (apart from some great work in https://github.com/rust-lang/rust/pull/76569 that unfortunately ran into preexisting soundness issues). It is slow and unsound, and we now have a destination propagation pass that performs a related optimization and could be extended. Closes https://github.com/rust-lang/rust/issues/36673 Closes https://github.com/rust-lang/rust/issues/73717 Closes https://github.com/rust-lang/rust/issues/76740
