cgraphunit.c (ipa_passes, compile): Reshedule symtab_remove_unreachable_nodes passes; update comments.

	* cgraphunit.c (ipa_passes, compile): Reshedule
	symtab_remove_unreachable_nodes passes; update comments.
	* ipa-inline.c (pass_data_ipa_inline): Do not schedule
	TODO_remove_functions before the pass; the functions ought to be
	already removed.
	* ipa.c (pass_data_ipa_free_inline_summary): Enable dump; schedule
	TODO_remove_functions.
	* passes.c (pass_data_early_local_passes): Do not schedule function
	removal.
	(execute_one_pass): Fix call of symtab_remove_unreachable_nodes.

	* lto.c (read_cgraph_and_symbols): Fix symtab_remove_unreachable_nodes
	call.
	(do_whole_program_analysis): Only sanity check that IPA passes cleans up.

	* testsuite/g++.dg/ipa/devirt-17.C: Update template.
