Form objc_storeStrong in the presence of bitcasts.
objc_storeStrong can be formed from a sequence such as
%0 = tail call i8* @objc_retain(i8* %p) nounwind
%tmp = load i8*, i8** @x, align 8
store i8* %0, i8** @x, align 8
tail call void @objc_release(i8* %tmp) nounwind
The code was already looking through bitcasts for most of the values
involved, but had missed one case where the pointer operand for the
store was a bitcast. Ultimately the pointer for the load and store
have to be the same value, after stripping casts.
