cc @dotnet/jit-contrib, @AndyAyersMS PTAL. Churn is quite big, and varies between platforms. This churn seems to be driven by LSRA visiting blocks in a different order. Would it make sense to instead visit blocks in RPO to make it layout-agnostic? cc @kunalspathak |

Follow-up to #107483. This had a lot of churn in both directions locally, though layout doesn't seem to have changed.
