> We duplicated the existing tests to have versions that toggle "reassoc" in IR rather than having separate RUN lines that use the (should-be-) deprecated global flag "-enable-unsafe-fp-math".
> Ideally, we could also replace the global "-fp-contract=fast" flag on the RUN line with "contract" FMF in IR. Not sure if we have underlying bugs there though.
