Dan Gohman e69b99baaf Implement operators |=, &=, and ^= for SmallBitVector, and remove the
restriction in BitVector for |= and ^= that the operand must be the
same length.

Dan Gohman 5976e7d5dd 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.
