----------------
This is unrelated to your change (but is debug-info related), sorry for the extra noise...

It looks like we early-out of `optimizePhiType` here if `II` has a user which doesn't match the conditions above (i.e. not a phi, store, or bitcast).  Couldn't this cause a change in behaviour based on debug-info if `II` is used by a debug intrinsic (`isa<DbgVariableIntrinsic>(V)`)?
