The function runtime.convT64 accepts a single uint64 argument, but the compiler's rules in the walk phase for determining whether is it ok to pass a value of type T to a call to runtime.convT64 were slightly off. In particular the test was allowing a type T with size less than eight bytes but with more than one internal element (e.g. a struct). This patch tightens up the rules somewhat to prevent this from happening. Updates #40724.
