	* gimplify.c (struct gimplify_ctx): Move to tree-gimple.h.
	(push_gimplify_context): Don't allocate temp_htab nor c itself here.
	Add c argument.
	(pop_gimplify_context): Check c->temp_htab instead of optimize whether
	htab_delete should be called.  Don't free c.
	(lookup_tmp_var): Create temp_htab lazily.
	(gimplify_scan_omp_clauses, gimplify_omp_parallel, gimplify_omp_task,
	gimplify_body, force_gimple_operand): Adjust push_gimplify_context
	callers.
	* omp-low.c (lower_omp_sections, lower_omp_single, lower_omp_master,
	lower_omp_ordered, lower_omp_critical, lower_omp_for,
