Thanks for following up.  The goal here is to merge the patches on the
(old) LTO branch which change the representation of TYPE_ARG_TYPES.  At
present, that is a TREE_LIST; on the LTO branch, this representation was
changed so that it was instead a TREE_VEC, which saves memory and makes
accesses more efficient.

The work remaining was to get these patches working with all of the
various back ends.  Some of them directly manipulate FUNCTION_TYPEs, and
so need changes.  If you would be willing to work on that, that would be
terrific!

Please let Kazu Hirta <kazu@codesourcery.com> or myself know if you need
help.

Thanks,
