Are there additional things we can get the compiler to do for us?  Some
things I've seen brought up:

 (1) Additional __atomic_*() ops could be useful.  Suggestions I've heard
     include direct LL/SC support - though the compiler people don't seem so
     keen on that.

 (2) -mmodel=kernel flag so that the compiler can optimise better for the
     kernel memory model.
