This addresses llvm.org/PR14699

Before:
template <typename T>
    void looooooooooooooooooooooongFunction(int Param1, int Param2);
template <typename T> void looooooooooooooooooooongFunction(

After:
template <typename T>
void looooooooooooooooooooooongFunction(int Param1, int Param2);
template <typename T>
void looooooooooooooooooooongFunction(int Paaaaaaaaaaaaaaaaaaaaram1,
                                      int Paaaaaaaaaaaaaaaaaaaaram2);
