If the address of a local is used in a comparison, AArch64 can fold the address-calculation into the comparison via "adds". Unfortunately, a couple of places (both hit in this one test) are not ready to deal with that yet and just assume the first source operand is a register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@316035 91177308-0d34-0410-b5e6-96231b3b80d8
