[cfe-dev] [PATCH]: Preparing AST for C++ declarations

[Argiris Kirtzidis]

Hi,

The attached patch contains these changes:

-New Decl subclasses:
    CXXField (derived from Field)  - instance fields
    CXXRecord (derived from Record)  - Records for C++
    CXXMethod (derived from Function)  - static and instance methods
    CXXClassVar (derived from Var)  - static data members

-Because there are two "types" of tags (Struct/CXXStruct etc.), to avoid 
constantly checking for both (i.e. when you need to know whether the 
Record is a 'struct' or 'union'),
 I've added a TagKind enum in TagDecl and a TagDecl::getTagKind method.
 Plus, RecordDecl/CXXRecordDecl::Create methods receive a 
TagDecl::TagKind enum instead of the general Decl::Kind enum.

-DeclContext gets a "ScopedDecl *DeclChain" member, which is used to 
chain decls that belong to the same DeclContext.
