Dan Gohman b74155db1e Update BitVectorTest.cpp to stay in sync with SmallBitVectorTest.cpp,
and fix a bug in BitVector's reference proxy class which this exposed.

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

Dale Johannesen 7c7b9a2807 Disable unittests/ADT/BitVectorTest on PPC Darwin.
It fails with a release build only, for reasons
as yet unknown.  (If there's a better way to Xfail
things here let me know, doesn't seem to be any
prior art in unittests.)

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.
