testcase changes for Fortran.
Bootstrapped/regtested on x86_64-linux.

OpenMP: Add Fortran support for inoutset depend-kind
Fortran additions to the C/C++ + ME/libgomp commit
r13-556-g2c16eb3157f86ae561468c540caf8eb326106b5f
gcc/fortran/ChangeLog:
* gfortran.h (enum gfc_omp_depend_op): Add OMP_DEPEND_INOUTSET.
(gfc_omp_clauses): Enlarge ENUM_BITFIELD.
* dump-parse-tree.cc (show_omp_namelist, show_omp_clauses): Handle
'inoutset' depend modifier.
* openmp.cc (gfc_match_omp_clauses, gfc_match_omp_depobj): Likewise.
* trans-openmp.cc (gfc_trans_omp_clauses, gfc_trans_omp_depobj):
Likewise.
libgomp/ChangeLog:
* libgomp.texi (OpenMP 5.1): Set 'inoutset' to Y.
(OpenMP Context Selectors): Add missing comma.
* testsuite/libgomp.fortran/depend-5.f90: Add inoutset test.
* testsuite/libgomp.fortran/depend-6.f90: Likewise.
* testsuite/libgomp.fortran/depend-7.f90: Likewise.
* testsuite/libgomp.fortran/depend-inoutset-1.f90: New test.
gcc/testsuite/ChangeLog:
* gfortran.dg/gomp/all-memory-1.f90: Add inoutset test.
* gfortran.dg/gomp/all-memory-2.f90: Likewise.
* gfortran.dg/gomp/depobj-1.f90: Likewise.
* gfortran.dg/gomp/depobj-2.f90: Likewise.
