Fix (aref vector (+ i constant)) with i negative on x86oids

 * The VOPs for indexed access with constant offset take a fixnum
   index. Adjust fndb entries to reflect that.

 * Fix FOLD-INDEX-ADDRESSING: don't convert if the resulting index
   would be wider than a fixnum, and compute the new offset correctly
   for subtractions.

 * Test case by Douglas Katzman.
