	* function.c (push_cfun): Check old current_function_decl matches
	old cfun, set new current_function_decl to the decl of the new
	cfun.
	(push_struct_function): Likewise.
	(pop_cfun): Likewise.
	(allocate_struct_function): Move call to
	invoke_set_current_function_hook to the end of the function.
	* cfgexpand.c (estimated_stack_frame_size): Do not set and restore
	current_function_decl.

	(cgraph_add_new_function): Likewise.
	(cgraph_analyze_function): Likewise.
	(assemble_thunk): Set cfun to NULL at the end.
	(expand_function): Move call to set_cfun downwards.
	* gimple-low.c (record_vars_into): Only check current_function_decl
	before possibly doing push_cfun.
	* gimplify.c (gimplify_function_tree): Do not set and restore
	current_function_decl.
	* ipa-inline-analysis.c (compute_inline_parameters): Likewise.
	(inline_analyze_function): Likewise.

	current_function_decl.
	* omp-low.c (finalize_task_copyfn): Likewise.
	(expand_omp_taskreg): Likewise.
	(create_task_copyfn): Likewise, move push_cfun up quite a bit.
	* passes.c (dump_passes): Do not set and restore current_function_decl.
	(do_per_function): Likewise.
	(do_per_function_toporder): Likewise.

	* tree-emutls.c (lower_emutls_function_body): Likewise.
	* tree-inline.c (initialize_cfun): Do not call pop_cfun.
	(tree_function_versioning): Do not call push_cfun, do not set and
	restore current_function_decl.  Remove assert checking consistency of
	cfun and current_function_decl.
	* tree-profile.c (tree_profiling): Do not set and restore
	current_function_decl.
	* tree-sra.c (convert_callers_for_node): Do not set
	current_function_decl.
