[PATCH] Minor ipa-prop.c internal interface tweak

Hi,
in order to use a few functions in the transformation phase of IPA-CP
without computing the whole struct ipa_node_params for the current
function, the following patch makes those functions (or their _1
versions) use just the vector they need.
Bootstrapped and tested on x86_64-linux, needed for the aggregate
IPA-CP.
OK for trunk?
Thanks,
Martin

* 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.
