combination of a load+objc_release; this is generally better for tools that try to track why values are retained and released. Also use objc_storeStrong when copying a block (again, only at -O0), which requires us to do a preliminary store of null in order to compensate for objc_storeStrong's assign semantics. llvm-svn: 166085
