The other option here is to leave the current behavior of asserting in `inferFromExprsList` on empty lists (which isn't btw specified/documented on the API doc comment) and instead update AffineMap::replace to handle the zero result case with an early return, and document the non-empty expectation on `inferFromExprsList`. But I felt removing those asserts was more systematic and complete.
