When estimating SROA savings, we want to see if an address is derived off an alloca in the caller. For store instructions, operand 1 is the address operand, but the current code uses operand 0. Use getPointerOperand for loads and stores to fix this. Patch by Easwaran Raman. http://reviews.llvm.org/D8425 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232827 91177308-0d34-0410-b5e6-96231b3b80d8
