Subject: [PATCH] Use the definition's source location even for already-instantiated templates (PR c++/46527)

This patch propagates the source location from a template function's
definition to any already-instantiated declarations. It doesn't also
copy it to the template_decl because that wasn't necessary to fix the
bug, but I'm happy to do so if the experts think I should..
