0d93b8d7 - [Async CC] Auth'd AFP ptr to load ptr from FunctionPointer.

[Async CC] Auth'd AFP ptr to load ptr from FunctionPointer. In FunctionPointer::getPointer, in the case that the FunctionPointer is actually a pointer to an AsyncFunctionPointer struct, the relative address of the function must be loaded from the AsyncFunctionPointer struct. Doing so requires authentication that pointer to the AsyncFunctionPointer struct. Here, that authentication is done.
