[cfe-commits] [PATCH] Improve the diagnostic for forgotten template arguments

[Jeffrey Yasskin]

>From the test:

namespace ns {
template<typename T> class B {};  // expected-note{{template is declared here}}
}
A<ns::B> a8; // expected-error{{class template-name ns::B requires
template arguments to produce a type}}

Clang used to just complain that the argument wasn't a type, which
confused users.
