Benjamin Kramer 8979e5f372 LVI: Recognize the form instcombine canonicalizes range checks into when forming constant ranges. ... This could probably be made a lot smarter, but this is a common case and doesn't require LVI to scan a lot of code. With this change CVP can optimize away the "shift == 0" case in Hashing.h that only gets hit when "shift" is in a range not containing 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151919 91177308-0d34-0410-b5e6-96231b3b80d8		2012-03-02 15:34:43 +00:00
