	* cgraph.h (compute_inline_parameters): Made public.
	* tree-pass.h (ipa_opt_pass): Removed function_generate_summary,
	variable_generate_summary, function_write_summary,
	variable_write_summary, variable_read_summary.  Added 
	generate_summary, write_summary, read_summary.
	* cgraphunit.c (cgraph_process_new_functions): Changed call from
	pass_ipa_inline.function_generate_summary, to
	compute_inline_parameters. 
	* ipa-inline.c (compute_inline_parameters): Made public and added
	node parameter.
	(compute_inline_parameters_for_current): New function.
	(pass_inline_param): Now calls
	compute_inline_parameters_for_current.
	(inline_generate_summary): Removed parameter and made to loop over
	all cgraph nodes.
	(pass_ipa_inline): Updated for new IPA_PASS structure.
	* passes.c (execute_ipa_summary_passes): Now is called once per
	pass rather than once per node*pass.
