        Description

        Two assertion failures:

        "registers must be different" assertion failure in MacroAssembler::atomic_cas_bool. Caused by LR being reused as a temporary.

        dhw->is_neutral() assertion failure in ObjectSynchronizer::fast_exit caused by MacroAssembler::fast_lock on ARM32 not respecting correct biased locking protocol.
