Patch to clean up wasted space

[Jason Merrill]

save_eh_status has been calling the wrong function all along.  The current
code in init_eh is useless; the code that used the type was removed a while
back.

push_function_context_to doesn't need to call init_emit;
init_function_start will do that, and calling it here needlessly allocates
space on the permanent_obstack.

	* except.c (init_eh): Do nothing.
	(save_eh_status): Call init_eh_for_function, not init_eh.
	* function.c (push_function_context_to): Don't call init_emit.
