Does one use has_trivial_copy or has_nothrow_copy to determine if a 
class has a copy constructor or not ?

I am writing some code that can do different things depending on whether 
a particular class has a copy constructor or does not have a copy 
constructor. I do not really care whether the copy constructor is a 
compiler generated copy constructor or not.
