[Bug c++/14912] Do not print default template arguments in error messages

The first non-trivial issue is that, in order to print "std::vector<int>" 
instead of "std::vector<int, std::allocator<int> >", we need to do the template 
substitution at error printing time, and check if the resulting substitution 
match. Either that, or I need to mark template arguments with a flag if they 
come from the template-id.

Also, should we skip default arguments also in lines like this:

test.cc: In member function `void A<T, N, X>::foo() [with T = int, int N = 0, 
int X = 1]':

We would be left with something like :

test.cc: In member function `void A<T, N, X>::foo() [with T = int]':

I assume that sounds about right, even if it might be surprising at first why 
the "with" clause does not show all the parameters.
