Implement special desugaring for numeric comparisons in PSI2IR

Browse Source 
This introduces the following IR built-in functions required for proper
implementation of the number comparisons:

- ieee754Equals(T, T): Boolean,
    for each T in {Float?, Double?}

- less(T, T): Boolean
  lessOrEqual(T, T): Boolean
  greater(T, T): Boolean
  greaterOrEqual(T, T): Boolean
    for each T in {Int, Long, Float, Double}
