This patch moves several tests introduced by the following patch:

commit
r14-325-gcacf65d74463600815773255e8b82b4043432bd7
into the proper location for OpenACC testing (thanks to Thomas for
spotting my mistake!), and also fixes a few additional problems --
missing diagnostics for non-pointer attaches, and a case where a pointer
was incorrectly dereferenced. Tests are also adjusted for vector-length
warnings on nvidia accelerators.

* openmp.cc (resolve_omp_clauses): Add diagnostic for
non-pointer/non-allocatable attach/detach.
* trans-openmp.cc (gfc_trans_omp_clauses): Remove dereference for
pointer-to-scalar derived type component attach/detach. Fix
attach/detach handling for descriptors.
