omp-expand.c (expand_omp_for_static_nochunk, [...]): For nowait worksharing loop with conditional lastprivate clause(s)...

	* omp-expand.c (expand_omp_for_static_nochunk,
	expand_omp_for_static_chunk): For nowait worksharing loop with
	conditional lastprivate clause(s), emit GOMP_loop_end_nowait call
	at the end.

	* c-c++-common/gomp/lastprivate-conditional-5.c: New test.
