* function.c: Define current_function_cannot_inline.

	(push_function_context_to): Save it.
	(pop_function_context_from): Restore it.
	* function.h (struct function): Provide it a home.
	* output.h: Declare it.
	* integrate.c (function_cannot_inline_p): Check it.
	* decl.c (cp_finish_decl): Disable inlining of extern inlines
	with static variables.
