* sim/mips/hilo-hazard-[123].s: New files.
* sim/mips/basic.exp (run_hilo_test): New procedure.
(models): Only list models that are included in the configuration.
(submodels): New variable, set to submodels of the above.
(mips64vr-*-elf, mips64vrel-*-elf): New configuration stanza.
Run hilo-hazard-[123].s.
