* gcc.dg/pr16194.c: We now output error on all three functions, not just

	first one.

	* cgraph.c: Include tree-flow.h
	(cgraph_add_new-function): Handle IPA_SSA mode; execute
	early_local_passes.
	* cgraph.h (enum cgraph_state): Add CGRAPH_STATE_IPA_SSA.
	* tree-pass.h (pass_all_early_optimizations): Declare.
	* cgraphunit.c (cgraph_process_new_functions): Add IPA_SSA; execute
	early_local_passes.
	(cgraph_analyze_function): Do early_local_passes.
	* tree-mudflap.c (mf_decl_cache_locals, mf_build_check_statement_for):
	Do not add referenced vars.
	* tree-optimize.c (gate_all_optimizations): Do not execute when not in
	SSA form.
	(gate_all_early_local_passes): New gate.
	(pass_early_local_passes): Use new gate.
	(execute_early_local_optimizations): New functions.
	(gate_all_early_optimizations): New gate.
	(pass_all_early_optimizations): New pass.
	(execute_free_datastructures): Free SSA only when initialized.
	(gate_init_datastructures): Init only when optimizing.
	(tree_lowering_passes): Do early local passes when called late.
	* tree-profile.c (do_tree_profiling): Don't profile functions added
	late.
	(do_early_tree_profiling, pass_early_tree_profile): Kill.
	* tree-cfg.c (update_modified_stmts): Do not update when operands are
	not active.
	* passes.c (init_optimizations_passes): Reorder so we go into SSA
	during early_local_passes.
	* Makefile.in (cgraph.o): Add dependency on tree-flow.h.
