    OpenACC: Stand-alone attach/detach clause fixes for Fortran [PR109622]

    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.
