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
