Integer lesser than or equal comparison. All comparison operations produce 0 or 1 values of the operand width.
leq(conditioncode) → op r0
operands: like Identity [xx:x]
Gets the equal or lesser than condition code of the ganged operation and puts it on the belt.
related operations: eql, neq, gtr, geq, lss, carry, overflow, fault
