Comment parsing tests: move tests where they belong

comment-misc-tags.m is mostly about miscellaneous Doxygen tags.  Move out tests
that check if the comment is attached to an ObjC decl.  Because the exitsting
test for this is in C++ (annotate-comments.cpp), create a new test --
annotate-comments-objc.m.

The rest of comment-misc-tags.m should be also moved elsewhere.

Comment parsing tests: move tests where they belong

Move C++-specific tests that were checking if we attach a base class comment to
a derived class to an existing test comment-to-html-xml-conversion.cpp.  Note
that the original testing approach was not actually testing the class--comment
relationship.  It only checked that we attached the comment *somewhere*.

The rest of subclass-comment.mm should be also moved elsewhere.

Omit llvm:: before makeArrayRef. We have using directive in this file.
