Code which repros the bug.

When compiling with either `-fvisibility=hidden` or
`-fvisibility-inlines-hidden`, templated class methods inside a templated class
do not respect the visibility attribute (e.g.
`__attribute__((visibility("default")))`) and remain hidden.

Repro code:

template<typename T>
class A {
  int a;
public:
  template<typename C>
  __attribute__ ((visibility ("default")))
  static void foo() {}
};

void func() {
  A<int>::foo<int>();
}


Then run, on the above code:
$ clang  -c -fvisibility=hidden -o test.o test.cpp
$ readelf -s test.o  # shows `void A<int>::foo<int>()` is HIDDEN</pre>
