  [SCEVExpander] Reuse removePointerBase() for canonical addrecs

ExposePointerBase() in SCEVExpander implements basically the same
functionality as removePointerBase() in SCEV, so reuse it.

The SCEVExpander code assumes that the pointer operand on adds is
the last one -- I'm not sure that always holds. As such this might
not be strictly NFC.
