JAX REVERTS BREAKING CHANGE, SYNCS XLA UPSTREAM

A changelist that hit production got rolled back twice in 12 hours, signaling either a critical regression or a coordination miss that JAX caught before it spread.

The JAX team reverted changelist 961233365 not once but twice, with copybara-service and Jinliang Wei both rolling back the same commit [1][2]. The identical reverts of 57df5685 suggest this wasn't a merge conflict or stale code, but a deliberate decision to kill something that landed. Simultaneously, the team pulled in a fresh XLA dependency pointing to upstream revision 7c3dd19 [3], which hints the problem may have been a version mismatch or an XLA API shift that broke on import. With only 2 commits and 1 PR across the period, this is focused work: undo what broke, sync what matters, move on.
