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.

it does make sense to keep them together, at least for now.

dyn_castNotVal in the X+~X transform.  dyn_castNotVal is
dramatic overkill for what the xform needed.

32c0cf5af9 inline the 'AddRHS' transformation, simplifying things significantly.
Eliminate the 'AddMaskingAnd' transformation, it is redundant with this
more general code right below it:
  // A+B --> A|B iff A and B have no bits set in common.

d0db8e8bad remove massive over-genality manifested as a big template
that got instantiated.  There is no reason for instcombine
to try this hard for simple associative optimizations.  Next
up, eliminate the template completely.
