Tobias Burnus b752eed3e3 OpenMP: Add support for 'self_maps' to the 'require' directive 
'self_maps' implies 'unified_shared_memory', except that the latter
also permits that explicit maps copy data to device memory while
self_maps does not. In GCC, currently, both are handled identical.

gcc/c/ChangeLog:

	* c-parser.cc (c_parser_omp_requires): Handle self_maps clause.

gcc/cp/ChangeLog:

	* parser.cc (cp_parser_omp_requires): Handle self_maps clause.

gcc/fortran/ChangeLog:

	* gfortran.h (enum gfc_omp_requires_kind): Add OMP_REQ_SELF_MAPS.
	(gfc_namespace): Enlarge omp_requires bitfield.
	* module.cc (enum ab_attribute, attr_bits): Add AB_OMP_REQ_SELF_MAPS.
	(mio_symbol_attribute): Handle it.
	* openmp.cc (gfc_check_omp_requires, gfc_match_omp_requires): Handle
	self_maps clause.
	* parse.cc (gfc_parse_file): Handle self_maps clause.

gcc/ChangeLog:

	* lto-cgraph.cc (output_offload_tables, omp_requires_to_name): Handle
	self_maps clause.
	* omp-general.cc (struct omp_ts_info, omp_context_selector_matches):
	Likewise for the associated trait.
	* omp-general.h (enum omp_requires): Add OMP_REQUIRES_SELF_MAPS.
	* omp-selectors.h (enum omp_ts_code): Add
	OMP_TRAIT_IMPLEMENTATION_SELF_MAPS.

include/ChangeLog:

	* gomp-constants.h (GOMP_REQUIRES_SELF_MAPS): #define.

libgomp/ChangeLog:

	* plugin/plugin-gcn.c (GOMP_OFFLOAD_get_num_devices):
	Accept self_maps clause.
	* plugin/plugin-nvptx.c (GOMP_OFFLOAD_get_num_devices):
	Likewise.
	* libgomp.texi (TR13 Impl. Status): Set to 'Y'.
	* target.c (gomp_requires_to_name, GOMP_offload_register_ver,
	gomp_target_init): Handle self_maps clause.
	* testsuite/libgomp.fortran/self_maps.f90: New test.

gcc/testsuite/ChangeLog:

	* c-c++-common/gomp/declare-variant-1.c: Add self_maps test.
	* c-c++-common/gomp/requires-4.c: Likewise.
	* gfortran.dg/gomp/declare-variant-3.f90:  Likewise.
	* c-c++-common/gomp/requires-2.c: Update dg-error msg.
	* gfortran.dg/gomp/requires-2.f90: Likewise.
	* gfortran.dg/gomp/requires-self-maps-aux.f90: New.
	* gfortran.dg/gomp/requires-self-maps.f90: New.
