  Log Message:
  -----------
  [ADT] Make use of subsetOf and anyCommon methods of BitVector (NFC)

Replace the code along these lines

    BitVector Tmp = LHS;
    Tmp &= RHS;
    return Tmp.any();

and

    BitVector Tmp = LHS;
    Tmp.reset(RHS);
    return Tmp.none();

with `LHS.anyCommon(RHS)` and `LHS.subsetOf(RHS)`, correspondingly, which
do not require creating temporary BitVector and can return early.
