clang-format: Always wrap before multi-line parameters/operands.

Before:
  aaaaaaaaaaaaaaaaaa(aaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa::
                                   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                     aaaaaaaaaaaaaaaaaaaaa);

After:
  aaaaaaaaaaaaaaaaaa(aaaaaaaa,
                     aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa::
                         aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                     aaaaaaaaaaaaaaaaaaaaa);

No new test cases, as the existing ones cover this fairly well.
