XLA:TPU Compiler Bug Affecting Token Selection

A precision mismatch bug in the XLA:TPU compiler caused incorrect token selection by the approximate top-k operation, affecting Haiku 3.5 and potentially Sonnet 4 and Opus 3. The issue was masked by a previous workaround that was inadvertently removed.
