Don't silently drop out-of-range bits in BitSetT Notes: - std::bitset's constructor accepts out-of-range bits (and drops them) - std::bitset with initializer list doesn't exist and is a BitSetT feature - |=, &= and ^= with non-bitset is a BitSetT feature - std::bitset's set(pos), reset(pos) and flip(pos) throw an exception if pos is out of the range of the bitset. This change adds an ASSERT in the functions that std::bitset would throw an exception, as well as functions that are only in BitSetT.
