"infer-address-spaces" pass replaces all refinable generic pointers with equivalent specific pointers. At -O0 optimisation level, infer-address-spaces pass doesn't run in the pipeline. "amdgpu-sw-lower-lds" pass instruments memory operations on addrspace(3) ptrs. Since, extra addrspacecasts are present from lds to flat addrspaces at -O0 and the actual store/load memory instructions are now on flat addrspace, these addrspacecast need to be handled in the amdgpu-sw-lower-lds pass itself. This patch lowers the lds ptr first to the corresponding ptr in the global memory from the asan_malloc. Then replaces the original cast with addrspacecast from global ptr to flat ptr.
