Now that LOG_LINKS are per regno, we can distribute them on PARALLELs
just fine.  Do so.  This makes PARALLELs not lose their LOG_LINKS early
when e.g. a trivial reg-reg move is combined, so that they can be used
in more useful combinations as well.

	* combine.c (distribute_links): Handle multiple SETs.
