- Rebased on the dependent changes, D102774 <https://reviews.llvm.org/D102774>
- Removed the separate RUN lines from both strict-fadd.ll & scalable-strict-fadd.ll for different VF/UFs.
- The tests now use one RUN line with the `-hints-allow-reordering=false` flag. This uses the existing CHECK lines in the tests, which prior to these changes only tested vectorization where reordering was allowed.
