upgrade-xla

You must look for the latest commit hash in the OpenXLA GitHub repository. You must make all necessary updates in ryft to switch us over to this new commit by following the steps described in the Contribution section of the crates/ryft-xla-sys/README.md file.

Note that you must always start by creating a new branch called u/eaplatanios/upgrade-xla-<commit> and pushing a change to crates/ryft-xla-sys/WORKSPACE updating the XLA commit hash and checksum. Then, you must submit a GitHub workflow to build the ryft-xla-sys binary dependencies for that commit. You can check in on the status of that workflow every 10 minutes though it can sometimes take a couple hours to complete. While that is happening, you can start working on the other steps described in crates/ryft-xla-sys/README.md. You will eventually need to wait for that workflow to complete before you can test your changes with the new binaries, but that should not block you from making all necessary code changes that you will want to test later on.
