Standalone attach and detach clauses should not create present/release
mappings for Fortran array descriptors (e.g. used when we have a pointer
to an array), both because it is unnecessary and because those mappings
will be incorrectly subject to reference counting. Simply omitting the
mappings means we just use GOMP_MAP_TO_PSET and GOMP_MAP_{ATTACH,DETACH}
mappings for array descriptors.
That requires a tweak in gimplify.c, since we may now see GOMP_MAP_TO_PSET
without a preceding data-movement mapping.

* trans-openmp.c (gfc_trans_omp_clauses): Don't create present/release
mappings for array descriptors.
gcc/
* gimplify.c (gimplify_omp_target_update): Allow GOMP_MAP_TO_PSET
without a preceding data-movement mapping.
gcc/testsuite/
* gfortran.dg/goacc/attach-descriptor.f90: Update pattern output. Add
scanning of gimplify dump.
libgomp/
* testsuite/libgomp.oacc-fortran/attach-descriptor-1.f90: Don't run for
shared-memory devices. Extend with further checking.
