Rather than having an alternative for systems where this is not true, this patch changes the test to check that a global copy propagation occurs in cprop2. This should work accross all ARM targets (it works when targetting Cortex-M0, Cortex-M3 and whatever default core for ARMv7-a with vfpv3-d16 FPU).
