Description: Jump if EQP and if not EQP would replace most internal calls to EQP, IEQP, and possibly EQ. Currently, IEQP compiles as a IDIFFERENCE/EQ, which doesn''t work for  (IEQP X MIN.FIXP) for example, because it overflows. In addition, EQP is pretty slow. We don''t have too many ufn/jumps, so the UFN will be a bit tricky.'
