PR rust-lang#63580 broke miri's ability to run the run-pass test suite with MIR optimizations enabled. The issue was that we weren't properly handling the substs and DefId associated with a Promoted value. This didn't break anything in rustc because in rustc this code runs before the Inliner pass which is where the DefId and substs can diverge from their initial values. It broke Miri though because it ran this code again after running the optimization pass.
