Uses of clang_getSpellingLocation should eventually move to calling
clang_getFileLocation, and clang_getSpellingLocation should do what
its name represents and actually point at the 'spelling' location, e.g.
inside a macro definition if the spelling of a token came from that.

that were already parsed in the same "indexing session".
An indexing session is defined as using the same CXIndexAction object
for multiple clang_indexSourceFile calls.
Passing CXIndexOpt_SkipParsedBodiesInSession as an indexing option will
enable the mode where we try to skip bodies that were already parsed in
another translation unit.
If a function's body was skipped, the "flags" field in the CXIdxDeclInfo
structure will have "CXIdxDeclFlag_Skipped" bit was set.

Because PNaCl bitcode must be target-independent, it uses some
different bitcode representations from other targets (e.g. byval and
sret for structures). This means that without additional type
information, it cannot meet some native ABI requirements for some
targets (e.g. passing structures containing unions by value on
x86-64). To allow generation of code which uses the correct native
ABIs, we also support triples such as x86_64-nacl, which uses
target-dependent IR (as opposed to le32-nacl, which uses byval and
sret).
To allow interoperation between the two types of code, this patch adds
a calling convention attribute to be used in code compiled with the
target-dependent triple, which will generate code using the le32-style
bitcode. This calling convention does not need to be explicitly
supported in the backend because it determines bitcode representation
rather than native conventions (the backend just needs to undersand
how to handle byval and sret for the Native Client OS).
This patch implements __attribute__((pnaclcall)) to generate calls in
bitcode according to the le32 bitcode conventions, an attribute which
is accepted by any Native Client target, but issues a warning
otherwise.

The ASTUnit needs to initialize an ASTWriter at the beginning of
parsing to fully handle serialization of a translation unit that
imports modules. Do this by introducing an option to enable it, which
corresponds to CXTranslationUnit_ForSerialization on the C API side.

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.

The implementation also includes a Relax NG schema and tests for the schema
itself. The schema is used in c-index-test to verify that XML documents we
produce are valid. In order to do the validation, we add an optional libxml2
dependency for c-index-test.

Christopher. Thanks!

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.

For a C++ method: the call is virtual.
For an ObjC message: the receiver is an object instance, not 'super' or a
specific class.

attached to a declaration in the completion string.
Since extracting comments isn't free, a new code completion option is
introduced.
A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

* Fix a glitchy "\param Returns..." to be "\returns";
* Fix parameter names given to \param, typos and otherwise.

mistakenly-generated Doxygen pages:
- Escaping @ symbols when Doxygen would otherwise incorrectly interpret them;
- Escaping # symbols when they're not intended as explicit Doxygen link
requests, such as when discussing preprocessor directives;
- In one odd case, unescaping @ in @__experimental_modules_import, because
Doxygen wrote '\@' to the output in that case, causing the example in the
description of ImportDecl to be wrong; and
- Fixing a typo: @breif -> @brief.
