This method is intended for use in places that cannot be reached with opaque pointers, or part of deprecated methods. This makes it easier to see that some uses of getPointerElementType() don't need further action.

I would also like to deprecate `PointerType::getElementType()` in favor of `Type::getPointerElementType()` in a followup. The `PointerType::getElementType()` method is annoying in that you cannot see at a glance whether this is actually accessing a pointer element type, a vector element type or an array element type. I'd like to reduce our TODO list to `grep getPointerElementType`.
