Add support for micromips tests.
* hilo-hazard-4.s: New file.
* testutils.inc (_dowrite): Changed reserved instruction encoding.
(writemsg): Moved the la and li instructions before the data they are
assigned to, which prevents a bug where MIPS32 relocations are used instead
of micromips relocations when building for micromips.
