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.

This can blow the stack with extremely deep hierarchies. Switch it to data-recursive.
This is implemented by introducing a post-children visitation callback that the
CursorVisitor is calling after child nodes of a cursor have been visited.
This is used by the annotate-tokens visitor to do extra work at that point.

This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.

if we have something like:
@synthesize prop = _prop;
and '_prop' is not declared, we will encounter a '_prop' ivar before
encountering the 'prop' synthesize declaration and we will think that
we passed the region-of-interest, missing the cursor for 'prop'.

Unless the user specifies, the clang used for static analysis is the one
found relative to scan-build.
If the user specifies -with-analyzer, they can pick either to use
the clang bundled with Xcode (via xcrun) or they can specify
a path to clang.

This is how Xcode lets individual files be marked as non-ARC when the rest
of the project is ARC-enabled, so this is necessary for scan-build xcodebuild.

Not only look for the comment near the declaration itself, but also walk the
redeclaration chain: the previous declaration might have had a documentation
comment.

rebuilds to serially link each tool, which is really really slow.
We still have to build libclang serially first because c-index-test
depends on it.

out.
Unfortunately, the existing makefiles for the extra repo don't specify
the correct library dependencies. Fixing that next. If you're following
along, you'll get linker errors.
