f3af311382 Teach libclang to walk the base and member initializers of a
constructor, in source order. Also introduces a new reference kind for
class members, which is used here (for member initializers) and will
also be used for designated initializers and offsetof.

901a0fabfc Implement libclang visitation for UnresolvedMemberExpr. This is the
last of the C++-specific expressions where we have decent source
information in the AST already. In particular, various
object-construction expressions (CXXNewExpr, CXXTemporaryObjectExpr)
still have poor source-location information that needs to be addressed.

3335f48448 Implement basic visitation for nested name specifiers via libclang
cursors. Sadly, this visitation is a hack, because we don't have
proper source-location information for nested-name-specifiers in the
AST. It does improve on the status quo, however.

a9aa29cf0b Implement libclang support for using declarations. Clang actually uses
three different kinds of AST nodes to represent using declarations:
UsingDecl, UnresolvedUsingValueDecl, and
UnresolvedUsingTypenameDecl. These three are collapsed into a single
cursor kind for using declarations, since libclang clients don't need
the distinction.

Several related changes here:
  - Cursor visitation of the three AST nodes for using declarations
  - Proper source-range computation for these AST nodes
  - Using declarations have no USRs, since they don't actually declare
    any entities.

9dc243c3eb Improve libclang indexing support for class template specializations
in a few related ways:

  - Don't recurse into instantiations of templates.
  - Recurse into explicit specializations.
  - Visit the template arguments of an explicit specialization or
    explicit instantiation.
  - Include template specialization arguments in the USRs for class
    template specializations.

f11309e194 Add a new libclang function clang_getTemplateCursorKind(), which
determines the kind of declaration that would be generated if the

among class/struct/union templates and function/member function/static
member function templates.

Also, teach clang_CXXMethod_isStatic() about function templates.

a23e8f7a0f Extend libclang with a new cursor kind that indicates a reference to a

within a template.

713602bb09 Implement basic support for indexing function templates in
libclang. This includes:
  - Cursor kind for function templates, with visitation logic
  - Cursor kinds for template parameters, with visitation logic
  - Visitation logic for template specialization types, qualified type
  locations
  - USR generation for function templates, template specialization
  types, template parameter types.

dcfba7b35b Generate Attr subclasses with TableGen.
Now all classes derived from Attr are generated from TableGen.
Additionally, Attr* is no longer its own linked list; SmallVectors or
Attr* are used. The accompanying LLVM commit contains the updates to
TableGen necessary for this.

Some other notes about newly-generated attribute classes:

 - The constructor arguments are a SourceLocation and a Context&,
   followed by the attributes arguments in the order that they were
   defined in Attr.td

 - Every argument in Attr.td has an appropriate accessor named getFoo,
   and there are sometimes a few extra ones (such as to get the length
   of a variadic argument).

Additionally, specific_attr_iterator has been introduced, which will
iterate over an AttrVec, but only over attributes of a certain type. It
can be accessed through either Decl::specific_attr_begin/end or
the global functions of the same name.

f4ade0ae3f As a heuristic, annotate tokens (via clang_annotateTokens) that are the arguments of a macro instantiation using the closest cursor with the same spelling location. Because macro arguments can get token pasted in any arbitrary order, we use the annotation map to paper over the token -> cursor annotations during our post-processing stage. This fixes most of <rdar://problem/8044584>, but still doesn't work for assert().

b14904c4a8 Implement caching of code-completion results for macro definitions
when the CXTranslationUnit_CacheCompletionResults option is given to
clang_parseTranslationUnit(). Essentially, we compute code-completion
results for macro definitions after we have parsed the file, then
store an ASTContext-agnostic version of those results (completion
string, cursor kind, priority, and active contexts) in the
ASTUnit. When performing code completion in that ASTUnit, we splice 
the macro definition results into the results provided by the actual
code-completion (which has had macros turned off) before libclang gets
those results. We use completion context information to only splice in
those results that make sense for that context.

With a completion involving all of the macros from Cocoa.h and a few other
system libraries (totally ~8500 macro definitions) living in a
precompiled header, we get about a 9% performance improvement from
code completion, since we no longer have to deserialize all of the
macro definitions from the precompiled header. 

Note that macro definitions are merely the canary; the cache is
designed to also support other top-level declarations, which should be
a bigger performance win. That optimization will be next.

Note also that there is no mechanism for determining when to throw
away the cache and recompute its contents.

8e984da800 Add code-completion support directly to ASTUnit, which performs code
completion within the translation unit using the same command-line
arguments for parsing the translation unit. Eventually, we'll reuse
the precompiled preamble to improve code-completion performance, and
this also gives us a place to cache results.

Expose this function via the new libclang function
clang_codeCompleteAt(), which performs the code completion within a
CXTranslationUnit. The completion occurs in-process
(clang_codeCompletion() runs code completion out-of-process).
