How about always using -fno-omit-frame-pointer, not as part of a user
option?  We could put it in some variable for those few (who?) who
might want to enable -fomit-frame-pointer.  I see no reason to expose
this to users, do you?

Alternatively, maybe the nativecomp code could be modified not to use
RBP?

Andrea, WDYT?

Thanks.
