This patch fixes several cases where multiple attach or detach mapping
nodes were being created for stand-alone attach or detach clauses
in Fortran. After the introduction of stricter checking later during
compilation, these extra nodes could cause ICEs, as seen in the PR.
The patch also fixes cases that "happened to work" previously where
the user attaches/detaches a pointer to array using a descriptor, and
(I think!) the "_data" field has offset zero, hence the same address as
the descriptor as a whole.
Tested with offloading to nvptx. OK?
LGTM for mainline and, after some grace period, for GCC 13.
Thanks,
Tobias
