possible fix v2 - shifting the special case output of objc_class_name_xxxx to
the back-end.

improved version (more logical in that it actually makes the reference into a
real reference in the absence of the hook).

built on i686-linux as well as i686-darwin9 ... seems to produce the expected
output on both.
