Fix anomaly when using typeclass resolution with filtered hyps in evars.
Make setoid_rewrite-through-rewrite's selection of occurences more robust: do not try unification with reduction if not needed. This changes a few scripts that were using reduction in a far from obvious way and could break more. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12562 85f007b7-540e-0410-9357-904b9bb8a0f7
