@nikic As you said, as soon as the `GEP`s are being updated to simple arithmetic operations, `PHI Translation`  would never be confused by `GEP` polymorphs. So this changeset along with this whole instruction-combining is going to be out of the picture. But still, for up until that point, I would suggest to fix this unprofitable `instCombine`

Is there anything else  I can do to help proceeding this changeset?
