Based on #115291.This PR proposes to enable the destination propagation pass by default.
This pass is meant to reduce the amount of copies present in MIR.
At the same time, this PR removes the
RenameReturnPlacepass, as it is currently unsound.DestinationPropagationis not limited to_0, but does not handle borrowed locals.
