Log:
gcc/
	* gimplify.c (omp_notice_variable): For references check
	whether what it refers to has mappable type, rather than
	the reference itself.
	(gimplify_scan_omp_clauses): Add support for
	GOMP_MAP_FIRSTPRIVATE_REFERENCE and GOMP_MAP_ALWAYS_POINTER,
	remove old handling of structure element based array sections.
	(gimplify_adjust_omp_clauses_1): For implicit references to
	variables with reference type and when not ref to scalar or
	ref to pointer, map what they refer to using tofrom and
	use GOMP_MAP_FIRSTPRIVATE_REFERENCE for the reference.
	(gimplify_adjust_omp_clauses): Remove GOMP_MAP_ALWAYS_POINTER
	from target exit data.  Handle GOMP_MAP_FIRSTPRIVATE_REFERENCE.
	Drop OMP_CLAUSE_MAP_PRIVATE support.
	* omp-low.c (scan_sharing_clauses): Handle
	GOMP_MAP_FIRSTPRIVATE_REFERENCE, drop OMP_CLAUSE_MAP_PRIVATE
	support.
	(lower_omp_target): Handle GOMP_MAP_FIRSTPRIVATE_REFERENCE
	and GOMP_MAP_ALWAYS_POINTER.  Drop OMP_CLAUSE_MAP_PRIVATE
	support.
	* tree-pretty-print.c (dump_omp_clause): Handle
	GOMP_MAP_FIRSTPRIVATE_REFERENCE and GOMP_MAP_ALWAYS_POINTER.
	Simplify.
	* tree-vect-stmts.c (vectorizable_simd_clone_call): Add
	SIMD_CLONE_ARG_TYPE_LINEAR_{REF,VAL,UVAL}_VARIABLE_STEP
	cases.
gcc/c/
	* c-parser.c (c_parser_omp_target_data,
	c_parser_omp_target_enter_data,
	c_parser_omp_target_exit_data, c_parser_omp_target): Allow
	GOMP_MAP_ALWAYS_POINTER.
	* c-typeck.c (handle_omp_array_sections): For structure element
	based array sections use GOMP_MAP_ALWAYS_POINTER instead of
	GOMP_MAP_FIRSTPRIVATE_POINTER.
	(c_finish_omp_clauses): Drop generic_field_head, structure
	elements are now always mapped even as array section bases,
	diagnose same var in data sharing and mapping clauses.
gcc/cp/
	* parser.c (cp_parser_omp_target_data,
	cp_parser_omp_target_enter_data,
	cp_parser_omp_target_exit_data, cp_parser_omp_target): Allow
	GOMP_MAP_ALWAYS_POINTER and GOMP_MAP_FIRSTPRIVATE_REFERENCE.
	* semantics.c (handle_omp_array_sections): For structure element
	based array sections use GOMP_MAP_ALWAYS_POINTER instead of
	GOMP_MAP_FIRSTPRIVATE_POINTER.
	(finish_omp_clauses): Drop generic_field_head, structure
	elements are now always mapped even as array section bases,
	diagnose same var in data sharing and mapping clauses.
	For references map what they refer to using GOMP_MAP_ALWAYS_POINTER
	for structure elements and GOMP_MAP_FIRSTPRIVATE_REFERENCE
	otherwise.
gcc/testsuite/
	* c-c++-common/gomp/clauses-2.c (foo): Adjust for diagnostics
	of variables in both data sharing and mapping clauses and for
	structure element based array sections being mapped rather than
	privatized.
include/
	* gomp-constants.h (enum gomp_map_kind): Add
	GOMP_MAP_ALWAYS_POINTER and GOMP_MAP_FIRSTPRIVATE_REFERENCE.
libgomp/
	* target.c (gomp_map_0len_lookup, gomp_map_val): New inline
	functions.
	(gomp_map_vars): Handle GOMP_MAP_ALWAYS_POINTER.  For
	GOMP_MAP_ZERO_LEN_ARRAY_SECTION use gomp_map_0len_lookup.
	Use gomp_map_val function.
	(gomp_exit_data): For GOMP_MAP_*ZERO_LEN* use
	gomp_map_0len_lookup instead of gomp_map_lookup.
	(omp_target_is_present): Use gomp_map_0len_lookup instead of
	gomp_map_lookup.
	* testsuite/libgomp.c/target-12.c (main): Adjust for
	omp_target_is_present change for one-past-last element.
	* testsuite/libgomp.c/target-17.c (foo): Drop tests where
	the same var is both mapped and privatized.
	* testsuite/libgomp.c/target-19.c (foo): Adjust for different
	handling of zero-length array sections.
	* testsuite/libgomp.c/target-29.c: New test.
	* testsuite/libgomp.c/target-30.c: New test.
	* testsuite/libgomp.c++/target-14.C: New test.
	* testsuite/libgomp.c++/target-15.C: New test.
	* testsuite/libgomp.c++/target-16.C: New test.
	* testsuite/libgomp.c++/target-17.C: New test.
	* testsuite/libgomp.c++/target-18.C: New test.
	* testsuite/libgomp.c++/target-19.C: New test.
