Our mips tests (running on a simulator) are broken as of this CL. Presumably
this is a simulator vs. hardware difference, could you please check and update
the simulator as necessary?

Simulator MIPS doesn't support yet SIMD extensions, we are still adding support.
In the meantime we are skipping SIMD tests on all buildbots since SIMD until
SIMD
lowering bugs get fixed.
