◆ isDeinterleavingMask()
Checks the given mask, and determines whether said mask is deinterleaving.
To be deinterleaving, a mask must increment in steps of 2, and either start with 0 or 1. (e.g. an 8x vector deinterleaving mask would be either <0, 2, 4, 6> or <1, 3, 5, 7>).

◆ isInstructionPairAdd()
◆ isInstructionPairMul()
◆ isInstructionPotentiallySymmetric()
◆ isInterleavingMask()
Checks the given mask, and determines whether said mask is interleaving.
To be interleaving, a mask must alternate between i and i + (Length / / 2), and must contain all numbers within the range of [0..Length) (e.g. a 4x vector interleaving mask would be <0, 2, 1, 3>).

◆ isNeg()
Returns true if the operation is a negation of V, and it works for both integers and floats.
