Subject: gimplify.c (gimplify_adjust_omp_clauses_1): Handle GOVD_FIRSTPRIVATE
 | GOVD_LASTPRIVATE.

	* gimplify.c (gimplify_adjust_omp_clauses_1): Handle
	GOVD_FIRSTPRIVATE | GOVD_LASTPRIVATE.
	(gimplify_adjust_omp_clauses): Simd region is never
	directly nested in combined parallel.  Instead, for linear
	with copyin/copyout, if in combined for simd loop, make decl
	firstprivate/lastprivate on OMP_FOR.
	* omp-low.c (expand_omp_for_generic, expand_omp_for_static_nochunk,
	expand_omp_for_static_chunk): When setting endvar, also set
	fd->loop.v to the same value.
