Nikita Popov bec7181d5b [SCEVExpander] Don't use recursive expansion for ptr IV inc ...

Similar to the non-ptr case, directly create the getelementptr
instruction. Going through expandAddToGEP() no longer makes sense
with opaque pointers, where generating the necessary instruction
is trivial.

This avoids recursive expansion of (the SCEV of) StepV while the
IR is in an inconsistent state, in particular with an incomplete
IV phi node, which utilities may not be prepared to deal with.
