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 llvm-svn: 232827
