Minor tweaks in ipa-inline.c

[Eric Botcazou <ebotcazou at adacore dot com>]

The usual typo and formatting issues, although there was a novelty since 
want_inline_function_to_all_callers_p used a consistent 3-space indentation.
The function also called twice node->ultimate_alias_target () for no valid 
reasons so the patch cleans that up too.  No functional changes.

Tested on x86_64-suse-linux, applied on mainline as obvious.

	* ipa-inline.c (want_inline_small_function_p): Fix typo and formatting.
	(want_inline_function_to_all_callers_p): Fix formatting and simplify.
