Reformat lines if they were "moved around".

An unwrapped line can get moved around if there is no newline before
it and the previous line was formatted.

Example:

  template<typename T>  // Cursor is on this line when hitting "format"
  T *getFETokenInfo() const { return static_cast<T*>(FETokenInfo); }

"return .." is the second unwrapped line in this scenario. I does not
touch any reformatted region. Thus, the result of formatting is:

  template <typename T> T *getFETokenInfo() const { return static_cast<T *>(FETokenInfo); }

After second format (and arguably desired end-result):

  template <typename T> T *getFETokenInfo() const {
      return static_cast<T *>(FETokenInfo);
  }

This fixes: llvm.org/PR15060.
