Given the specific instantiations we have of __move_merge, something like the
new draft I'm attaching seems correct and avoids the regressions for
inplace_merge. But actually it seems __first2 always == __result after the
first move, thus I think we really want to rework and possibly simplify these
__move_merge helpers.
