clang-format: Don't allow hanging indentation for operators on new lines

Before:
  if (aaaaaaaa && bbbbbbbbbbbbbbb // need to wrap
                  == cccccccccccccc) ...

After:
  if (aaaaaaaa
      && bbbbbbbbbbbbbbb // need to wrap
         == cccccccccccccc) ...

The same rule has already be implemented for BreakBeforeBinaryOperators
set to false in r205527.
