Reland "[arm] [simulator] Do also execute tests on real hardware" 

This is a reland of 8bacd848.
The failing test is disabled if not executing in the simulator.

Original change's description:
> [arm] [simulator] Do also execute tests on real hardware
> 
> In order to avoid writing tests that *only* pass in the simulator, but
> not on real hardware, do also execute the simulator tests on real
> hardware.
