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.

Improve formatting of builder-type calls.

Before:
aaaaaaa->aaaaaaa->aaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)->aaaaaaaa(aaaaaaaaaaaaaaa);

After:
aaaaaaa->aaaaaaa
    ->aaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaa(aaaaaaaaaaaaaaa);

Improve indentation of builder type calls.

In builder-type calls, it can be very confusing to just indent
parameters from the start of the line. Instead, indent 4 from the
correct function call.

Before:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
    aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()->aaaaaaaaaaaaaaaa(
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaaaaaaaaaaa();

After:
aaaaaaaaaaaaaaaaaaa()->aaaaaa(bbbbb)->aaaaaaaaaaaaaaaaaaa( // break
                                        aaaaaaaaaaaaaa);
aaaaaaaaaaaaaaaaaaaaaaa *aaaaaaaaa = aaaaaa->aaaaaaaaaaaa()
    ->aaaaaaaaaaaaaaaa(
        aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
    ->aaaaaaaaaaaaaaaaa();
