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