Remove extra uses of ClearAllBits
ArenaBitVector creation guarantees it starts empty. Add a debug
check to make sure this assumption doesn't change.
Note that ArenaAllocator guarantees zero-initialized memory but
ScopedArenaAllocators do not. This is fine either way since the
BitVector constructor calls ClearAllBits.
