Currently expandUnalignedLoad/Store uses place holder pointer info for temporary memory operand in stack, which does not have correct address space. This causes unaligned private double16 load/store to be lowered to flat_load instead of buffer_load for amdgcn target. This fixes failures of OpenCL conformance test basic/vload_private/vstore_private on target amdgcn---amdgizcl. Differential Revision: https://reviews.llvm.org/D35361 llvm-svn: 314566
