Dan Gohman 5035fbf91c Add a ConstantSignedRange class, which does for signed integers 
what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

adjustments to the unittests.

Jeffrey Yasskin 41f2477a50 Add tests for WeakVH and AssertingVH. These pointed out that the overloads for 
the comparison operators were not only unnecessary in the presence of the
implicit conversion; they caused ambiguous overload errors. So I deleted them.
