ObjCIndirectCopyRestoreExpr - Represents the passing of a function argument by indirect copy-restore in ARC. This is used to support passing indirect arguments with the wrong lifetime, e.g. when passing the address of a __strong local variable to an 'out' parameter. This expression kind is only valid in an "argument" position to some sort of call expression.
The parameter must have type 'pointer to T', and the argument must have type 'pointer to U', where T and U agree except possibly in qualification. If the argument value is null, then a null pointer is passed; otherwise it points to an object A, and:
- A temporary object B of type T is initialized, either by zero-initialization (used when initializing an 'out' parameter) or copy-initialization (used when initializing an 'inout' parameter).
- The address of the temporary is passed to the function.
- If the call completes normally, A is move-assigned from B.
- Finally, A is destroyed immediately.
Currently 'T' must be a retainable object lifetime and must be __autoreleasing; this qualifier is ignored when initializing the value.
