As Richard's suggested. We need to adapt doc for cond_len operations.

When operand 1 is true and element index < operand 5 + operand 6, perform an
operation on operands 2 and 3 and
store the result in operand 0, otherwise store operand 4 in operand 0.
+operand 4 should be well-defined value for reduction situation, and undefined
value for some arithmetic operations
+e.g. integer division.
The operation only works for the operands are vectors.
