Dan Gohman a3755d8d36 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75177 91177308-0d34-0410-b5e6-96231b3b80d8		2009-07-09 22:07:27 +00:00
