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.
