I don't think there is such switch, and for good reason. It's
usefulness would be pretty low, as "everything" would most probably
mean, that some options with n levels should be set to max. I tried to
compile code with such settings and "fix it", so no warnings would
appear. I gave up, amount of seemingly bogus warnings stemming from
some obscure, though probably valid, optimizations is gigantic and in
most cases fixing them makes code unreadable. Of course YMMV.

I really hate this damn machine, I wish that they would sell it.
It never does just what I want, but only what I tell it.
