Rules: 1. SCEVUnknown is a pointer if and only if the LLVM IR value is a pointer. 2. SCEVPtrToInt is never a pointer. 3. If any other SCEV expression has no pointer operands, the result is an integer. 4. If a SCEVAddExpr has exactly one pointer operand, the result is a pointer. 5. If a SCEVAddRecExpr's first operand is a pointer, and it has no other pointer operands, the result is a pointer. 6. If every operand of a SCEVMinMaxExpr is a pointer, the result is a pointer. 7. Otherwise, the SCEV expression is invalid. I'm not sure how useful rule 6 is in practice. If we exclude it, we can guarantee that ScalarEvolution::getPointerBase always returns a SCEVUnknown, which might be a helpful property. Anyway, I'll leave that for a followup. This is basically mop-up at this point; all the changes with significant functional effects have landed. Some of the remaining changes could be split off, but I don't see much point.
