/* Condition could be:
* - constant, true
* - constant, false
* - constant, NULL
* - non constant, non nullable_00431
* - non constant, nullable_00431
*
* Then and else could be:
* - constant, not NULL
* - constant, NULL
* - non constant, non nullable_00431
* - non constant, nullable_00431
*
* Thus we have 5 * 4 * 4 = 80 combinations.
