ipa-prop.c (ipa_get_param_decl_index_1): New function.

2012-11-06  Martin Jambor  <mjambor@suse.cz>

	* ipa-prop.c (ipa_get_param_decl_index_1): New function.
	(ipa_get_param_decl_index): Just call ipa_get_param_decl_index_1.
	(ipa_populate_param_decls): Accept descriptors parameter rather
	than the whole info.
	(load_from_unmodified_param): Likewise.
	(ipa_load_from_parm_agg_1): Likewise.
	(ipa_load_from_parm_agg): Extract descriptors from info.
	(compute_complex_assign_jump_func): Likewise.
	(ipa_analyze_indirect_call_uses): Likewise.
