clang-format: Fix bug in ObjC method declaration formatting.

Also disallow breaking between "@" and "{" or "[".

Before:
  - (NSAttributedString *)attributedStringForSegment:(NSUInteger)segment
                                               index:(NSUInteger)index
                                          attributes:(NSDictionary *)attributes
                                  nonDigitAttributes:(NSDictionary *)
      nonDigitAttributes;
  [mailComposeViewController
     setToRecipients:@
     [ NSBundle.mainBundle.infoDictionary[@"ABBFeedbackEmail"] ]];

After:
  - (NSAttributedString *)attributedStringForSegment:(NSUInteger)segment
                                               index:(NSUInteger)index
                                          attributes:(NSDictionary *)attributes
                                  nonDigitAttributes:
                                      (NSDictionary *)nonDigitAttributes;
  [mailComposeViewController
      setToRecipients:
          @[ NSBundle.mainBundle.infoDictionary[@"ABBFeedbackEmail"] ]];

This fixes llvm.org/PR18030.

clang-format: The "<" of a template argument is not a binary operator.

With Style.BreakBeforeBinaryOperators, clang-format breaks incorrectly.
This fixes llvm.org/PR17994.

Before:
  return boost::fusion::at_c<0>(iiii).second == boost::fusion::at_c
                                                <1>(iiii).second;

After:
  return boost::fusion::at_c<0>(iiii).second ==
         boost::fusion::at_c<1>(iiii).second;

clang-format: Fix incorrect space in parameters named by comment.

This fixes llvm.org/PR17979.
