This patch adds C_ORT_DECLARE_MAPPER and C_ORT_OMP_DECLARE_MAPPER
region types to the c_omp_region_type enum, and uses them in cp/pt.cc.
Previously the C_ORT_DECLARE_SIMD code was being abused to inhibit calling
finish_omp_clauses within mapper definitions, but this patch uses one
of the new enumeration values for that purpose instead.  This shouldn't
result in any behaviour change, but improves self-documentation.

gcc/c-family/
	* c-common.h (c_omp_region_type): Add C_ORT_DECLARE_MAPPER and
	C_ORT_OMP_DECLARE_MAPPER codes.

gcc/cp/
	* pt.cc (tsubst_omp_clauses): Use C_ORT_OMP_DECLARE_MAPPER.
	(tsubst_expr): Likewise.
