Personally, I think it could be nice with something like TTI->getMaximumVF()  or even getMaximumSLPVF()... Probably also good if with a test case for your target if possible that is supposed to not produce any spilling...

Please check D92059 <https://reviews.llvm.org/D92059>, I believe that is what we have discussed here.
