I think that the overloading of the word target is making it very
hard to understand each other.

Again, target_set_exec_dir would tell the inferior that, from now on,
the exec direction for all future resumes will be (forward|reverse).
If the target method is unset, then we know the feature is unsupported.
If it is set, and it fails, then refuse the change of direction -
feature not supported either.  Otherwise, update the infrun direction
with the new direction.
