--- Comment #2 from Michael Kruse <llvm at meinersbur.de> ---
Fix in 3b9677e1eced0eafc17bdf3f6a41f1fd7db9f120.

If you intend to make ScalarEvolution preserve the nsw flag even without the
stray udiv, you would need to fix the pr41656.ll test case and change the
"Invalid Context" to what it is in the new test case pr48783.ll which then
become identical.
