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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92730 91177308-0d34-0410-b5e6-96231b3b80d8
