2018-12-06  Richard Biener  <rguenther@suse.de>

	* df-problems.c (df_rd_local_compute): Use bitmap_release.
	(df_live_free): Likewise.
	(df_md_local_compute): Likewise.
	(df_md_free): Release df_md_scratch bitmap.
	* loop-invariant.c (calculate_loop_reg_pressure): Use
	bitmap_release.
	* sched-deps.c (true_dependency_cache, output_dependency_cache,
	anti_dependency_cache, control_dependency_cache,
	spec_dependency_cache): Use bitmap instead of bitmap_head *.
	* sched-ebb.c (schedule_ebbs_init): Initialize non-GTY
	dont_calc_deps as bitmap allocated from obstack not GC.
	(schedule_ebbs_finish): Use bitmap_release.
	* sched-rgn.c (schedule_insns): Initialize non-GTY
	not_in_df as bitmap allocated from obstack not GC.
	Use bitmap_release.
	* sel-sched.c (_forced_ebb_heads): Remove premature optimization.
	(sel_region_init): Allocate forced_ebb_heads.
	(sel_region_finish): Free forced_ebb_heads.
