The pointer size of the addrspacecasted pointer might not have matched, so this would have hit an assert in accumulateConstantOffset. I think this was here to allow constant folding of a load of an addrspacecasted constant. Accumulating the offset through the addrspacecast doesn't make much sense, so something else is necessary to allow folding the load through this cast. llvm-svn: 243300
