The following is it, changelog omits the boring part (enumerating
all files and pass structs touched ...).

	* passes.c (execute_todo): Do not call ggc_collect conditional here.
	(execute_one_ipa_transform_pass): But unconditionally here.
	(execute_one_pass): And here.
	(init_optimization_passes): Remove reload pass.
	* tree-pass.h (TODO_ggc_collect): Remove.
	(pass_reload): Likewise.
	* ira.c (do_reload): Merge into ...
	(ira): ... this.
	(rest_of_handle_reload): Remove.
	(pass_reload): Likewise.
	* config/i386/i386.c (ix86_option_override): Refer to ira instead
	of reload for vzeroupper pass placement.
	* <everywhere>: Remove TODO_ggc_collect from todo_flags_start
	and todo_flags_finish of all passes.
