Dmitri Gribenko 6bf8f803f2 Comment parsing: don't crash while parsing \deprecated in a standalone comment
(comment without a decl).

I think this can not happen during normal compilation with -Wdocumentation,
only while using Clang APIs to parse comments outside of a source file.

Based on a patch by Olivier Goffart.

Dmitri Gribenko 1e50cbf366 Comment parsing: fix a bug where a line with whitespace between two paragraphs
would cause us to concatenate these paragraphs into a single one.

The no-op whitespace churn in test/Index test happened because these tests
don't use the correct approach for testing and are more strict than required
for they are testing.

Dmitri Gribenko acf2e786d2 Comment parsing: add CommentOptions to allow specifying custom comment block commands
Add an ability to specify custom documentation block comment commands via a new
class CommentOptions.  The intention is that this class will hold future
customizations for comment parsing, including defining documentation comments
with specific numbers of parameters, etc.

CommentOptions instance is a member of LangOptions.

CommentOptions is controlled by a new command-line parameter
-fcomment-block-commands=Foo,Bar,Baz.

Fariborz Jahanian 1c883b9b57 [Doc parsing] This patch searches overridden objc/c++
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.

Dmitri Gribenko 7acbf00f96 Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.
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.

Dmitri Gribenko 34df220410 Comment parsing: add support for \tparam command on all levels.
The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this
breaks libclang binary compatibility, but should not be a problem since API is
so new.

This also fixes PR13372 as a side-effect.

Dmitri Gribenko 66a00c765f Fix PR13411: Comment parsing: failed assertion on unterminated verbatim block.
The assertion was wrong in case we have a verbatim block without a closing
command.

Also add tests for closing command name in a verbatim block, since now it can
be empty in such cases.

Dmitri Gribenko f26054f0fb Enable comment parsing and semantic analysis to emit diagnostics. A few
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).

Dmitri Gribenko ec92531c29 Implement AST classes for comments, a real parser for Doxygen comments and a
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.
