* cgraphunit.c (cgraph_estimate_size_after_inlining): Compute

	call cost based on argument sizes.
	(cgraph_mark_inline_edge): Avoid inline unit from shringking by
	inlining.
	* params.def: (max-inline-inssn-single): Set to 450.
	(max-inline-insns-auto): Set to 90.
	(max-inline-insns-recursive): Set to 450
	(max-inline-insns-recursive-auto): Set to 450.
	(large-function-insns): Set to 2700.
	(inline-call-cost): New parameter.
	* tree-inline.c (estimate_move_cost): New function.
	(estimate_num_insns_1): Compute move sizes costs by estimate_move_cost
	for non-gimple-regs, set cost to 0 for gimple-regs.  Compute call size
	based on arguments.
	* tree-inline.h (estimate_move_cost): Declare.
	* invoke.texi: (max-inline-inssn-single): Change default to 450.
	(max-inline-insns-auto): Change default to 90.
	(max-inline-insns-recursive): Change default to 450
	(max-inline-insns-recursive-auto): Change default to 450.
	(large-function-insns): Change default to 2700.
	(inline-call-cost): Document new parameter.

	* gcc.dg/winline-6.c: Modify so inlined function have nonzero cost.
