toplev.c (rest_of_compilation): Fix webizer pass ordering.

	* toplev.c (rest_of_compilation): Fix webizer pass ordering.

	* cgraphunit.c (decide_is_function_needed):  Fix test dealing
	with functions implicitly made inline.

	* cgraphunit.c (cgraph_decide_inlining_incrementally):  New function.
	(cgraph_finalize_function): Use it.
	(cgraph_mark_inline): Allow incrmental decisions
	* invoke.texi (max-inline-slope, min-inline-insns): Kill.
	* params.def (PARAM_MAX_INLINE_SLOPE, PARAM_MIN_INLINE_INSNS): Kill.
	* tree-inline.c (limits_allow_inlining): Kill.
	(expand_call_inline): Always use unit-at-a-time path.

	* decl.c (start_cleanup_fn):  Set DECL_DECLARED_INLINE_P to deffer
	the expansion.

	* testsuite/g++.dg/opt/inline4.C: Do not use min-inline-insns
	parameter.
	* testsuite/gcc.dg/inline-2.c: Likewise.
