On second thought, I'm not sure it's so simple. First of all, nobody in
the tree actually changes the default speed or safety settings, AFAICT.
On closer inspection, maybe that's been a good thing: cl--optimize-speed
and cl--optimize-safety are ordinary non-local variables, and
cl--do-proclaim just setqs them, indicating that compiling files that
change their optimization settings will have global effects. I'm not
sure we should change how it works now without having a discussion of
how we want this whole system to work.

Should we make cl--optimize-speed and cl--optimize-safety buffer-local?
And shouldn't we be setting the default values to 3 and 0, respectively,
during initial Emacs compilation when we haven't been given configured
with --enable-checking?

Also, we could make cl-locally do something useful by having it bind
cl--optimize-speed and cl--optimize-safety, then fully macroexpand its body.
