[PATCH] [GOMP4] OpenACC 1.0+ support in fortran front-end

[Ilmir Usmanov]

Hi Thomas!

I fixed these patches: 
http://gcc.gnu.org/ml/gcc-patches/2014-01/msg01520.html .

Instead of adding new OACC_* data structures and macros for OpenACC 
clauses these patches reuse existing OMP_* functionality and extends it. 
But OpenACC-specific constructs and directives still named as OACC_*.

Thomas, as I noticed you privately, I can't use OpenMP 4.0 map clause to 
represent OpenACC data clauses in front-end, so old form of them still 
there.

Successfully bootstrapped with no new regressions on 
x86_64-unknown-linux-gnu.

OK for gomp-4_0-branch?
