[patch,openacc] handle missing OMP_LIST_ clauses in fortran's parse tree debugger

This patch updates Fortran's parse tree printer to print the names of
new OpenACC data clauses. I'm not if this functionality is widely used
or not, but from a standpoint of correctness, this patch would probably
be nice to have.

It this patch OK for trunk? I bootstrapped and regtested it for x86_64
Linux with nvptx offloading.

Thanks,
Cesar

[OpenACC] handle missing OMP_LIST_ clauses in fortran's parse tree debugger

2018-XX-YY  Cesar Philippidis  <cesar@codesourcery.com>

	gcc/fortran/
	* dump-parse-tree.c (show_omp_clauses): Add missing omp list_types
	and reorder the switch cases to match the enum in gfortran.h.

(cherry picked from gomp-4_0-branch r228355, 159518d)
