[InstCombine] Erase old mul when creating umulo

As we don't return the result of replaceInstUsesWith(), we are
responsible for erasing the instruction.

There is a small subtlety here in that we need to do this after
the other uses of Builder, which uses the original multiply as
the insertion point.

NFC apart from worklist order changes.
