cfgrtl.c (rtl_delete_block): Fix comment.

	* cfgrtl.c (rtl_delete_block): Fix comment.
	* emit-rtl.c (remove_unnecessary_notes): Die if we see BLOCK_BEG
	or BLOCK_END insn notes.
	* jump.c (squeeze_notes): Likewise.
	* haifa-sched.c (reemit_notes): Don't "re-emit" EH_REGION_BEG and
	EH_REGION_END notes, we never have them to begin with.
	* sched-deps.c (sched_analyze_insn): When updating loop notes,
	verify that we have indeed only recorded loop notes.
	(sched_analyze): Die if we see EH_REGION_BEG or EH_REGION_END notes.
	Only record loop notes.

	* cfgexpand.c (tree_expand_cfg): Fix comment.

	* passes.c (rest_of_compilation): Don't do a second call to
	convert_from_eh_region_ranges from here, it's already called
	from cfgexpand.c.
	* except.c (resolve_fixup_regions): Remove.
	(remove_fixup_regions): Remove.
	(convert_from_eh_region_ranges_1): Remove.
	(convert_from_eh_region_ranges): Remove the case where EH is
	not already lowered at the tree level.  We always lower there.
