- Remove redundant casting - Cheaper final XOR parity flip (~/^1 instead of != 0) - Support XOR reduction of ~XOR nodes - Don't add redundant masking of terms - Support unmasked terms - Add cheaper implementation for single bit only terms - Ensure result is clean under all circumstances (this fixes current bugs)
