At -O0, prefer objc_storeStrong with a null new value to the 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@166085 91177308-0d34-0410-b5e6-96231b3b80d8
