[RFC] Another fix for PR c++/41183

[Jie Zhang]

Hi Jakub,

I just found another way to fix this PR. Why not copy cfun->language 
when we create function clones as the attached patch does. I encountered 
another similar issue, that means I need to add cp_function_chain 
checking in another place. This patch could fix both cases. This patch 
has been bootstrapped and regtested with 
--enable-languages=c,c++,objc,fortran on gcc-4.4 branch. Testing on 
trunk with an adapted patch looks OK, too. How would you like this fix?


Regards,
