This patch introduces a match_acc function to the fortran FE. It's
almost identical to match_omp, but it passes openacc = true to
gfc_match_omp_clauses. I supposed I could have consolidated those two
functions, but they are reasonably simple so I left them separate. Maybe
a follow up patch can consolidate them. I was able to eliminate a lot of
duplicate code with this function.

Is this ok for trunk and gcc-6?

The patch seems to be reverse. If I regard the "-" lines as additions
and the "+" lines as deletions, it makes sense and is in line with
the ChangeLog and what you wrote above.

Otherwise, it looks good to me.

Yeah, patch -R + commit is ok with me.
