[PATCH] (C++ patch) Fix obj-c++/23640, not registering classes for the GNU runtime

[Andrew Pinski <pinskia at physics dot uc dot edu>]

The problem here is that we don't create the constructor function to 
call the
objc front-end created construction function which means we don't 
register
classes for the GNU runtime.  This fixes about 11 test failures on 
targets
with the GNU runtime as the standard runtime.

OK? Bootstrapped and tested on powerpc-darwin and on x86_64-linux-gnu
with no regressions.

Thanks,
Andrew Pinski

cp/ChangeLog:

	* decl2.c (cp_finish_file): If this is obj-c++ and we need a static 
init,
	call generate_ctor_or_dtor_function.
