declared in.

Richard Trieu aa5e256c20 Change the self-reference visitor (which gives the warning for self-reference oninitalization warning of -Wuninitialized) to exclude member variables that can decay into pointers. This will cause it to no longer warn on this code:
struct foo { char a[100], *e; } bar = { .e = bar.a };

Douglas Gregor e8bbc12152 Extend the ASTContext constructor to delay the initialization of
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

Fariborz Jahanian 97d744bea4 objective-c: this patch (re)introduces objective-c's default property

It will become the default feature soon.

Douglas Gregor 081425343b Introduce support for a simple module import declaration, which
loads the named module. The syntax itself is intentionally hideous and
will be replaced at some later point with something more
palatable. For now, we're focusing on the semantics:
  - Module imports are handled first by the preprocessor (to get macro
  definitions) and then the same tokens are also handled by the parser
  (to get declarations). If both happen (as in normal compilation),
  the second one is redundant, because we currently have no way to
  hide macros or declarations when loading a module. Chris gets credit
  for this mad-but-workable scheme.
  - The Preprocessor now holds on to a reference to a module loader,
  which is responsible for loading named modules. CompilerInstance is
  the only important module loader: it now knows how to create and
  wire up an AST reader on demand to actually perform the module load.
  - We search for modules in the include path, using the module name
  with the suffix ".pcm" (precompiled module) for the file name. This
  is a temporary hack; we hope to improve the situation in the
  future.

Eli Friedman 3fa64df543 Refactor and fix checking for initialization of flexible array members. The old version had the checks scattered across the code, missed some checks, and had a couple nasty bugs in existing checks.

Fariborz Jahanian d6d866d6fa objective-c: Bring objective-c handling of decl context
to modernity. Instead of passing down individual
context objects from parser to sema, establish decl

minor cleanups.

Francois Pichet 00c7e6ceb1 Implement function template specialization at class scope extension in Microsoft mode. A new AST node is introduced: ClassScopeFunctionSpecialization. This node holds a FunctionDecl that is not yet specialized; then during the class template instantiation the ClassScopeFunctionSpecialization will spawn the actual function specialization.
Example:
template <class T>
class A {
public:
  template <class U> void f(U p) {  }
  template <> void f(int p) {  } // <== class scope specialization
};

This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code.
BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error.

Douglas Gregor 9767347b11 Encapsulate the Objective-C id/Class/SEL "redefinition" types in
ASTContext with accessors/mutators. The only functional change is that
the AST writer won't bother writing the id/Class/SEL redefinition type
if it hasn't been explicitly set; previously, it ended up being
written as a synonym for the built-in id/Class/SEL.

Kaelyn Uhrain 7d9bc633d2 Match type names and give more info for out-of-line function definition errors.
Having a function declaration and definition with different types for a
parameter where the types have same (textual) name can occur when an unqualified
type name resolves to types in different namespaces in each location.

The error messages have been extended by adding notes that point to the first
parameter of the function definition that doesn't match the declaration, instead
of a generic "member declaration nearly matches". The generic message is still
used in cases where the mismatch is not in the paramenter list, such as
mismatched cv qualifiers on the member function itself.

Douglas Gregor dc5c958602 Make Sema::LocallyScopedExternalDecls lazily deserialized. In theory,
we could turn this into an on-disk hash table so we don't load the
whole thing the first time we need it. However, it tends to be very,
very small (i.e., empty) for most precompiled headers, so it isn't all
that interesting.

John McCall d2930c2100 In Objective-C, pull arbitrary attributes from overridden
methods, including indirectly overridden methods like those
declared in protocols and categories.  There are mismatches
that we would like to diagnose but aren't yet, but this   
is fine for now.

I looked at approaches that avoided doing this lookup 
unless we needed it, but the infer-related-result-type
checks were doing it anyway, so I left it with the same
fast-path check for no previous declartions of that 
selector.
