8a58b8f83b Revert the part of 75177 that split ConstantRange into two classes, and 
merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

33251eff97 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.

dc96a23780 Apply Jeffrey Yasskin's CallbackVH patch, with minor tweaks from me 
to make the copy constructor and destructor protected, and corresponding
adjustments to the unittests.

114afdef8b 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.
