Same case as for memset and memcpy, but this time for clobbering stores and loads. We still can't allow coercion to or from non-integrals, regardless of the transform. Now that I'm done the whole little sequence, it seems apparent that we'd entirely missed reasoning about clobbers in the original GVN support for non-integral pointers. My appologies, I thought we'd upstreamed all of this, but it turns out we were still carrying a downstream hack which hid all of these issues. My chanks to Cherry Zhang for helping debug. llvm-svn: 354407
