Add support for allocate clause (OpenMP 5.0).

This patch adds support for OpenMP 5.0 allocate clause for fortran. It does not
yet support the allocator-modifier as specified in OpenMP 5.1. The allocate
clause is already supported in C/C++.

gcc/fortran/ChangeLog:

	* dump-parse-tree.c (show_omp_clauses): Handle OMP_LIST_ALLOCATE.
	* gfortran.h (OMP_LIST_ALLOCATE): New enum value.
	* openmp.c (enum omp_mask1): Add OMP_CLAUSE_ALLOCATE.
	(gfc_match_omp_clauses): Handle OMP_CLAUSE_ALLOCATE
	(OMP_PARALLEL_CLAUSES, OMP_DO_CLAUSES, OMP_SECTIONS_CLAUSES)
	(OMP_TASK_CLAUSES, OMP_TASKLOOP_CLAUSES, OMP_TARGET_CLAUSES)
	(OMP_TEAMS_CLAUSES, OMP_DISTRIBUTE_CLAUSES)
	(OMP_SINGLE_CLAUSES): Add OMP_CLAUSE_ALLOCATE.
	(OMP_TASKGROUP_CLAUSES): New.
	(gfc_match_omp_taskgroup): Use OMP_TASKGROUP_CLAUSES instead of
	OMP_CLAUSE_TASK_REDUCTION.
	(resolve_omp_clauses): Handle OMP_LIST_ALLOCATE.
	(resolve_omp_do): Avoid warning when loop iteration variable is
	in allocate clause.
	* trans-openmp.c (gfc_trans_omp_clauses): Handle translation of
	allocate clause.
	(gfc_split_omp_clauses): Update for OMP_LIST_ALLOCATE.
