Re: Turn on SMS by default on ARM

SMS flags to use for testing:

Would we expect -funsafe-loop-optimizations to be turned on as well by default ? I would expect that to be used for peak tuning rather than anything else.

Also I suspect we only want to turn this on for v7-a cores and not for anything earlier and probably not for the M-class cores given that code size is of higher importance there than the wins we'd get with SMS.
