opts.c (decode_options): Do not fiddle with inlining parameters in case of optimizing for size. 

* opts.c (decode_options): Do not fiddle with inlining
	parameters in case of optimizing for size.
	* ipa-inline.c (cgraph_decide_recursive_inlining): When optimizing
	for size do nothing.
	(cgraph_decide_inlining_of_small_function): When optimizing for
	size never inline functions increasing caller size.
	(cgraph_early_inlining): Inline for size when optimizing for size.
