Fortran: Implement OpenMP 5.1 scope construct
Fortran version to commit e45483c7c4badc4bf2d6ced22360ce1ab172967f,
which implemented OpenMP's scope construct for C and C++.
Most testcases are based on the C testcases; it also contains some
testcases which existed previously but had no Fortran equivalent.
gcc/fortran/ChangeLog:
* dump-parse-tree.c (show_omp_node, show_code_node): Handle
EXEC_OMP_SCOPE.
* gfortran.h (enum gfc_statement): Add ST_OMP_(END_)SCOPE.
(enum gfc_exec_op): Add EXEC_OMP_SCOPE.
* match.h (gfc_match_omp_scope): New.
* openmp.c (OMP_SCOPE_CLAUSES): Define
(gfc_match_omp_scope): New.
(gfc_match_omp_cancellation_point, gfc_match_omp_end_nowait):
Improve error diagnostic.
(omp_code_to_statement): Handle ST_OMP_SCOPE.
(gfc_resolve_omp_directive): Handle EXEC_OMP_SCOPE.
* parse.c (decode_omp_directive, next_statement,
gfc_ascii_statement, parse_omp_structured_block,
parse_executable): Handle OpenMP's scope construct.
* resolve.c (gfc_resolve_blocks): Likewise
* st.c (gfc_free_statement): Likewise
* trans-openmp.c (gfc_trans_omp_scope): New.
(gfc_trans_omp_directive): Call it.
* trans.c (trans_code): handle EXEC_OMP_SCOPE.
libgomp/ChangeLog:
* testsuite/libgomp.fortran/scope-1.f90: New test.
* testsuite/libgomp.fortran/task-reduction-16.f90: New test.

* gfortran.dg/gomp/scan-1.f90:
