re PR fortran/60928 (gfortran issue with allocatable components and OpenMP)

	PR fortran/60928
	* omp-low.c (lower_rec_input_clauses) <case OMP_CLAUSE_LASTPRIVATE>:
	Set lastprivate_firstprivate even if omp_private_outer_ref
	langhook returns true.
	<case OMP_CLAUSE_REDUCTION>: When calling omp_clause_default_ctor
	langhook, call unshare_expr on new_var and call
	build_outer_var_ref to get the last argument.
gcc/c-family/
	* c-pragma.c (omp_pragmas_simd): Move PRAGMA_OMP_TASK...
	(omp_pragmas): ... back here.
gcc/fortran/
	* f95-lang.c (gfc_init_builtin_functions): Handle -fopenmp-simd
	like -fopenmp.
	* openmp.c (resolve_omp_clauses): Remove allocatable components
	diagnostics.  Add associate-name and intent(in) pointer
	diagnostics for various clauses, diagnose procedure pointers in
	reduction clause.
	* parse.c (match_word_omp_simd): New function.
	(matchs, matcho): New macros.
	(decode_omp_directive): Change match macros to either matchs
	or matcho.  Handle -fopenmp-simd.
	(next_free, next_fixed): Handle -fopenmp-simd like -fopenmp.
	* scanner.c (skip_free_comments, skip_fixed_comments, include_line):
	Likewise.
	* trans-array.c (get_full_array_size): Rename to...
	(gfc_full_array_size): ... this.  No longer static.
	(duplicate_allocatable): Adjust caller.  Add NO_MEMCPY argument
	and handle it.
	(gfc_duplicate_allocatable, gfc_copy_allocatable_data): Adjust
	duplicate_allocatable callers.
	(gfc_duplicate_allocatable_nocopy): New function.
	(structure_alloc_comps): Adjust g*_full_array_size and
	duplicate_allocatable caller.
	* trans-array.h (gfc_full_array_size,
	gfc_duplicate_allocatable_nocopy): New prototypes.
	* trans-common.c (create_common): Call gfc_finish_decl_attrs.
	* trans-decl.c (gfc_finish_decl_attrs): New function.
	(gfc_finish_var_decl, create_function_arglist,
	gfc_get_fake_result_decl): Call it.
	(gfc_allocate_lang_decl): If DECL_LANG_SPECIFIC is already allocated,
	don't allocate it again.
	(gfc_get_symbol_decl): Set GFC_DECL_ASSOCIATE_VAR_P on
	associate-names.
	* trans.h (gfc_finish_decl_attrs): New prototype.
	(struct lang_decl): Add scalar_allocatable and scalar_pointer
	bitfields.
	(GFC_DECL_SCALAR_ALLOCATABLE, GFC_DECL_SCALAR_POINTER,
	GFC_DECL_GET_SCALAR_ALLOCATABLE, GFC_DECL_GET_SCALAR_POINTER,
	GFC_DECL_ASSOCIATE_VAR_P): Define.
	(GFC_POINTER_TYPE_P): Remove.
	* trans-openmp.c (gfc_omp_privatize_by_reference): Don't check
	GFC_POINTER_TYPE_P, instead test GFC_DECL_GET_SCALAR_ALLOCATABLE,
	GFC_DECL_GET_SCALAR_POINTER or GFC_DECL_CRAY_POINTEE on decl.
	(gfc_omp_predetermined_sharing): Associate-names are predetermined.
	(enum walk_alloc_comps): New.
	(gfc_has_alloc_comps, gfc_omp_unshare_expr_r, gfc_omp_unshare_expr,
	gfc_walk_alloc_comps): New functions.
	(gfc_omp_private_outer_ref): Return true for scalar allocatables or
	decls with allocatable components.
	(gfc_omp_clause_default_ctor, gfc_omp_clause_copy_ctor,
	gfc_omp_clause_assign_op, gfc_omp_clause_dtor): Fix up handling of
	allocatables, handle also OMP_CLAUSE_REDUCTION, handle scalar
	allocatables and decls with allocatable components.
	(gfc_trans_omp_array_reduction_or_udr): Don't handle allocatable
	arrays here.
	(gfc_trans_omp_reduction_list): Call
	gfc_trans_omp_array_reduction_or_udr even for allocatable scalars.
	(gfc_trans_omp_do_simd): If -fno-openmp, just expand it as OMP_SIMD.
	(gfc_trans_omp_parallel_do_simd): Likewise.
	* trans-types.c (gfc_sym_type): Don't set GFC_POINTER_TYPE_P.
	(gfc_get_derived_type): Call gfc_finish_decl_attrs.
