XML comment for declarations which pretty-prints
declaration. I had to XFAIL one test annotate-comments.cpp.
This test is currently unmaintainable as written.
Dmitri G., can you see what we can do about this test.
We should change this test such that adding a new tag does not wreck
havoc to the test.

methods looking for documentation on a particular base
class inherited by any method that overrides the base class.
In case of redeclaration, as when objc method is defined
in the implementation, it also looks up for documentation
in class/class extension being redeclared.

Now we have a list of all commands. This is a good thing in itself, but it
also enables us to easily implement typo correction for command names.
With this change we have objects that contain information about each command,
so it makes sense to resolve command name just once during lexing (currently we
store command names as strings and do a linear search every time some property
value is needed). Thus comment token and AST nodes were changed to contain a
command ID -- index into a tables of builtin and registered commands. Unknown
commands are registered during parsing and thus are also uniformly assigned an
ID. Using an ID instead of a StringRef is also a nice memory optimization
since ID is a small integer that fits into a common bitfield in Comment class.
This change implies that to get any information about a command (even a command
name) we need a CommandTraits object to resolve the command ID to CommandInfo*.
Currently a fresh temporary CommandTraits object is created whenever it is
needed since it does not have any state. But with this change it has state --
new commands can be registered, so a CommandTraits object was added to
ASTContext.
Also, in libclang CXComment has to be expanded to include a CXTranslationUnit
so that all functions working on comment AST nodes can get a CommandTraits
object. This breaks binary compatibility of CXComment APIs.
Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't
need TU parameter anymore, so it was removed. This is a source-incompatible
change for this C API.

despite __attribute__(__used__). As explained by Argyrios,

The fix is to use these functions from another .o file.
Thanks, Argyrios!

diagnostics implemented -- see testcases.
I created a new TableGen file for comment diagnostics,
DiagnosticCommentKinds.td, because comment diagnostics don't logically
fit into AST diagnostics file. But I don't feel strongly about it.
This also implements support for self-closing HTML tags in comment
lexer and parser (for example, <br />).
In order to issue precise diagnostics CommentSema needs to know the
declaration the comment is attached to. There is no easy way to find a decl by
comment, so we match comments and decls in lockstep: after parsing one
declgroup we check if we have any new, not yet attached comments. If we do --
then we do the usual comment-finding process.
It is interesting that this automatically handles trailing comments.
We pick up not only comments that precede the declaration, but also
comments that *follow* the declaration -- thanks to the lookahead in
the lexer: after parsing the declgroup we've consumed the semicolon
and looked ahead through comments.
Added -Wdocumentation-html flag for semantic HTML errors to allow the user to
disable only HTML warnings (but not HTML parse errors, which we emit as
warnings in -Wdocumentation).

very simple semantic analysis that just builds the AST; minor changes for lexer
to pick up source locations I didn't think about before.
Comments AST is modelled along the ideas of HTML AST: block and inline content.
* Block content is a paragraph or a command that has a paragraph as an argument
or verbatim command.
* Inline content is placed within some block. Inline content includes plain
text, inline commands and HTML as tag soup.
