Simon Pilgrim 34e7243464 [DAG] Fold freeze(bitcast(x)) -> bitcast(freeze(x)) ...

This is a very specific fold to fix an upstream poor codegen issue.

InstCombine has the much more flexible pushFreezeToPreventPoisonFromPropagating but I don't think we're quite there with DAG/TLI handling for canCreateUndefOrPoison/isGuaranteedNotToBeUndefOrPoison value tracking yet.

Fixes #54911
