Fixes a miscompile introduced in r204912. It would miscompile code like (unsigned)(a + -49) <= 5U. The transform would turn this into (unsigned)a < 55U, which would return true for values in [0, 49], when it should not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204948 91177308-0d34-0410-b5e6-96231b3b80d8
