Detailed Description

Utility class representing a non-constant Xor-operand.

We classify non-constant Xor-Operands into two categories: C1) The operand is in the form "X & C", where C is a constant and C != ~0 C2) C2.1) The operand is in the form of "X | C", where C is a non-zero constant. C2.2) Any operand E which doesn't fall into C1 and C2.1, we view this operand as "E | 0"
