[PATCH] D103255: [LV] Mark increment of main vector loop induction variable as NUW.

LGTM as well.  I'm not super familiar with this code, but I skimmed the callers and the necessary conditions seemed to be locally implied.

As an aside, do you have a test case where SCEV can't figure this out?  I've got D103118 <https://reviews.llvm.org/D103118> out for review now, and am interested in other such cases.
