[SCEV] Be more aggressive in proving NUW ... for AddRec's in loops for which SCEV is unable to compute a max tripcount. This is the NUW variant of r269211 and fixes PR27691. (Note: PR27691 is not a correct or stability bug, it was created to track a pending task). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@269790 91177308-0d34-0410-b5e6-96231b3b80d8
