Both GCC and Clang return the same value for `__bdos(*ptr->array)` with my new
change. For `__bdos(&ptr->array)` GCC returns -1 and Clang returns the
calculated value (it does that even without this patch). So it's behavior that
existed before the advent of `__counted_by` and is probably wrong, but maybe
not? People have different expectations for `__bdos` in various situations it
seems...
I'm tempted to leave it as is since it isn't a regression, unless you have
strong feelings about it.
