CBQI BV: Add handling for missing operators. (#1274)
This adds inverse handling for BITVECTOR_XOR, BITVECTOR_SIGN_EXTENDS, BITVECTOR_COMP, BITVECTOR_ASHR. Function isInvertible() now corresponds to exactly the operators (plus index) for which we can determine an inverse, which avoids traversing along non-invertible paths.
This further enables a test case that I missed to enable in PR #1268.
