> Original change's description:

> > 
> > Some tests were recently added to test-simulator-arm.cc, however this file is
> > meant for tests that are specific to the simulator and therefore are not written
> > to work on hardware. While this sounds surprising, the reason is that our simulation
> > of synchronisation instructions is more conservative than on hardware.
> > 
> > To make this more clear, this patch renames the "test-simulator-arm{,64}.cc"
> > files to "test-sync-primitives-arm{,64}.cc", and moves the vneg and vabs tests
> > into "test-assembler-arm.cc" which is were tests that are garanteed to work in
> > either native or simulated environments live.
> > 
> > Finally, take the opportunity to share a little bit of code.
