clang-format: Fix corner case in overloaded operator definitions.

Before:
  SomeLoooooooooooooooooooooooooogType operator>
      >(const SomeLooooooooooooooooooooooooogType &other);
  SomeLoooooooooooooooooooooooooogType // break
      operator>>(const SomeLooooooooooooooooooooooooogType &other);

After:
  SomeLoooooooooooooooooooooooooogType
  operator>>(const SomeLooooooooooooooooooooooooogType &other);
  SomeLoooooooooooooooooooooooooogType // break
  operator>>(const SomeLooooooooooooooooooooooooogType &other);

This fixes llvm.org/PR16328.
