Subject: For class template implicit instantiation, also update its location to point
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=734bd6e25c349248634d1d0c5d7127c4868331b0;p=clang

For class template implicit instantiation, also update its location to point
to the pattern template that it came from, otherwise we had this situation:

template <typename T1, typename T2>
struct S {
};

template <typename T>
struct S<T, int> {
};

void f() {
  S<int, int> s; // location of declaration "S<int, int>" was of "S<T1, T2>" not "S<T, int>"
}
