* ipa-inline.c: Fix comment typos; do not inline gt-ipa-inline.h
	(want_inline_function_called_once_p): Break out the logic from
	ipa_inline.
	(edge_badness): Ensure that profile is not misupdated.
	(lookup_recursive_calls): Prioritize by call frequencies.
	(inline_small_functions): Move program size estimates here;
	actually process whole queue even when unit growth has been
	met. (to properly compute inline_failed reasons and for the
	case unit size decrease.) Revisit comments on recursive
	inlining.
	(ipa_inline): Remove unit summary code; first inline hot calls
	of functions called once, cold calls next.
	(order, nnodes): Remove unused variables.
	* Makefile.in (ipa-inline.o): No longer depent on ggc files.
	(GTFILES): Remove ipa-inline.c
	* sel-sched.c (fill_insns): Silence uninitialized var warning.
