1.0.4.87: better EQUALP hash function for arrays

        * Hashing on just the first 4 elements makes EQUALP tables essentially
          useless for many kinds of data due to collisions. Hash all the
          elements.
        * Optimize a couple of other cases that are probably common
          (u-b 8 vectors, fixnum vectors).
        * Change EQUALP-HASH to punt to EQ-HASH when appropriate
