Update BitVectorTest.cpp to stay in sync with SmallBitVectorTest.cpp,

and fix a bug in BitVector's reference proxy class which this exposed.

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

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.
