Clang chokes on commas in template argument lists in dependent template-ids in
certain contexts.

### SOURCE:
$ cat dependentTemplateComma.cc
template <typename EncTraits> struct A {
   void foo(int = EncTraits::template TypeEnc<int, int>::val);
};


### COMPILER INVOCATION AND OUTPUT:
$ /build/clang/workdir/Debug+Asserts/bin/clang++ dependentTemplateComma.cc -c
dependentTemplateComma.cc:2:55: error: expected ')'
   void foo(int = EncTraits::template TypeEnc<int, int>::val);
                                                      ^
dependentTemplateComma.cc:2:12: note: to match this '('
   void foo(int = EncTraits::template TypeEnc<int, int>::val);
           ^
dependentTemplateComma.cc:2:50: error: expected '>'
   void foo(int = EncTraits::template TypeEnc<int, int>::val);
