openmp: Add support for enter clause on declare target

Browse source 
OpenMP 5.1 and earlier had 2 different uses of to clause, one for target
update construct with one semantics, and one for declare target directive
with a different semantics.
Under the hood we were using OMP_CLAUSE_TO_DECLARE to represent the latter.
OpenMP 5.2 renamed the declare target clause to to enter, the old one is
kept as a deprecated alias.

As we are far from having full OpenMP 5.2 support, this patch adds support
for the enter clause (and renames OMP_CLAUSE_TO_DECLARE to OMP_CLAUSE_ENTER
with a flag to tell the spelling of the clause for better diagnostics),
but doesn't deprecate the to clause on declare target just yet (that
should be done as one of the last steps in 5.2 support).

gcc/
	* tree-core.h (enum omp_clause_code): Rename OMP_CLAUSE_TO_DECLARE
	to OMP_CLAUSE_ENTER.
	* tree.h (OMP_CLAUSE_ENTER_TO): Define.
	* tree.cc (omp_clause_num_ops, omp_clause_code_name): Rename
	OMP_CLAUSE_TO_DECLARE to OMP_CLAUSE_ENTER.
	* tree-pretty-print.cc (dump_omp_clause): Handle OMP_CLAUSE_ENTER
	instead of OMP_CLAUSE_TO_DECLARE, if OMP_CLAUSE_ENTER_TO, print
	"to" instead of "enter".
	* tree-nested.cc (convert_nonlocal_omp_clauses,
	convert_local_omp_clauses): Handle OMP_CLAUSE_ENTER instead of
	OMP_CLAUSE_TO_DECLARE.
gcc/c-family/
	* c-pragma.h (enum pragma_omp_clause): Add PRAGMA_OMP_CLAUSE_ENTER.
gcc/c/
	* c-parser.cc (c_parser_omp_clause_name): Parse enter clause.
	(c_parser_omp_all_clauses): For to clause on declare target, use
	OMP_CLAUSE_ENTER clause with OMP_CLAUSE_ENTER_TO instead of
	OMP_CLAUSE_TO_DECLARE clause.  Handle PRAGMA_OMP_CLAUSE_ENTER.
	(OMP_DECLARE_TARGET_CLAUSE_MASK): Add enter clause.
	(c_parser_omp_declare_target): Use OMP_CLAUSE_ENTER instead of
	OMP_CLAUSE_TO_DECLARE.
	* c-typeck.cc (c_finish_omp_clauses): Handle OMP_CLAUSE_ENTER instead
	of OMP_CLAUSE_TO_DECLARE, to OMP_CLAUSE_ENTER_TO use "to" as clause
	name in diagnostics instead of
	omp_clause_code_name[OMP_CLAUSE_CODE (c)].
gcc/cp/
	* parser.cc (cp_parser_omp_clause_name): Parse enter clause.
	(cp_parser_omp_all_clauses): For to clause on declare target, use
	OMP_CLAUSE_ENTER clause with OMP_CLAUSE_ENTER_TO instead of
	OMP_CLAUSE_TO_DECLARE clause.  Handle PRAGMA_OMP_CLAUSE_ENTER.
	(OMP_DECLARE_TARGET_CLAUSE_MASK): Add enter clause.
	(cp_parser_omp_declare_target): Use OMP_CLAUSE_ENTER instead of
	OMP_CLAUSE_TO_DECLARE.
	* semantics.cc (finish_omp_clauses): Handle OMP_CLAUSE_ENTER instead
	of OMP_CLAUSE_TO_DECLARE, to OMP_CLAUSE_ENTER_TO use "to" as clause
	name in diagnostics instead of
