Subject: sbitmap: Remove popcount

In r193072 sbitmap_popcount was removed, so we cannot ask for the popcount
of an sbitmap anymore.  Nothing calls sbitmap_alloc_with_popcount either.
This patch removes everything else popcount-related from sbitmap.


	* cfganal.c (bitmap_intersection_of_succs): Delete assert checking
	dst->popcount.
	(bitmap_intersection_of_preds): Ditto.
	(bitmap_union_of_succs): Ditto.
	(bitmap_union_of_preds): Ditto.
	* sbitmap.c (do_popcount): Delete.
	(BITMAP_DEBUGGING): Delete.
	(sbitmap_verify_popcount): Delete.
	(sbitmap_alloc): Don't initialize the popcount field.
	(sbitmap_alloc_with_popcount): Delete.
	(sbitmap_resize): Don't resize the popcount array.
	(sbitmap_vector_alloc): Don't initialize the popcount field.
	(bitmap_copy): Don't copy the popcount array.
	(bitmap_clear): Don't clear the popcount array.
	(bitmap_clear): Delete the popcount array handling.
	(bitmap_ior_and_compl): Delete the popcount assert.
	(bitmap_not): Ditto.
	(bitmap_and_compl): Ditto.
	(bitmap_and): Delete the popcount array handling.
	(bitmap_xor): Ditto.
	(bitmap_ior): Ditto.
	(bitmap_or_and): Delete the popcount assert.
	(bitmap_and_or): Ditto.
	(popcount_table): Delete.
	(sbitmap_elt_popcount): Delete.
	* sbitmap.h (simple_bitmap_def): Delete the popcount field.
	(bitmap_set_bit): Delete the popcount assert.
	(bitmap_clear_bit): Ditto.
	(sbitmap_free): Don't free the popcount array.
	(sbitmap_alloc_with_popcount): Delete declaration.
	(sbitmap_popcount): Ditto.
