This isn't ready to land yet because I have to fix all the compile errors. 
That's being done in separate changelists.

Note that is_convertible is different from is_base_of, but it's easier to
implement.  So I did it instead, because it is Good Enough (tm).

I defer completely to James on this one.

LGTM. Good luck landing this without bustage :)

http://codereview.chromium.org/3549010/diff/2001/3004
File base/template_util.h (right):

http://codereview.chromium.org/3549010/diff/2001/3004#newcode17
base/template_util.h:17: };
should these go into the internal namespace?

why isn't big_ defined:

struct big_ {
  small_ dummy[2];
};

Thanks for the review.  Yeah, I'll probably break something.  So it goes.
