> I did leave the legacy behavior as an option since a) loop-flatten stops triggering if I extend due to weirdly specific pattern matching I didn't understand and b) we could reasonably use the mode if we'd externally established a lock of overflow.
I wasn't aware of this until I noticed the FIXME and have committed NFC patches rGf6ac8088b0e8 <https://reviews.llvm.org/rGf6ac8088b0e890765974fee5f5820a340736f9bf> and rGada6d78a7802 <https://reviews.llvm.org/rGada6d78a7802f8057f1ab7cee0bed25f91fcc4b4> to try and clarify this.
