fab4c9e9df Add an all() method to BitVector, for testing whether all bits are set.

b252fbd179 Implement a read/write operator[] for SmallBitVector with a proxy class.

1e44aa0412 Make sure SmallBitVector actually uses the small case and fix latent bugs.
- We can't use PointerIntPair here since we require the discrimination bit to be in the LSB.

e7962c9897 Implement operators |=, &=, and ^= for SmallBitVector, and remove the
restriction in BitVector for |= and ^= that the operand must be the
same length.

ad2cee44e0 Some versions of GCC don't like non-static data members in sizeof
in this context.

cb89afc965 Add a SmallBitVector class, which mimics BitVector but uses only
a single pointer (PointerIntPair) member. In "small" mode, the
pointer field is reinterpreted as a set of bits. In "large" mode,
the pointer points to a heap-allocated object.

Also, give BitVector empty and swap functions.

And, add some simple unittests for BitVector and SmallBitVector.
