ASTLocation is a much better name for its intended purpose which to represent a "point" into the AST.

of a top-level declaration loads another top-level declaration of the
same name whose type depends on the first declaration having been
completed. This commit breaks the circular dependency by delaying
loads of top-level declarations triggered by loading a name until we
are no longer recursively loading types or declarations.

Fix <rdar://problem/7033733>.  The CF_RETURNS_RETAINED attribute should work if the return type on an Objective-C method is a CF type reference, not just an Objective-C object reference.

'index-test' is now able to provide additional info for a Decl, through multiple AST files:
-Find declarations
-Find definitions
-Find references

llvm-svn: 74803

Its purpose is to provide the basic infrastructure for cross-translation-unit analysis like indexing, refactoring, etc.

Currently it is very "primitive" and with no type-names support. It can provide functionality like
"show me all references of this function from these translation units".

DeclReferenceMap (similar to ParentMap) is a helper class for mapping Decls to the AST nodes that reference them.
A client will initialize it by passing an ASTContext to its constructor and later use it to iterate over
the references of a Decl.
References are mapped and retrieved using the primary declaration (Decl::getPrimaryDecl()) of a particular Decl.

llvm-svn: 74801

When a Decl subclass can have multiple re-declarations in the same declaration context (like FunctionDecl),
getPrimaryDecl() will return a particular Decl that all of them will point to as the "primary" declaration.

ASTNode is an immutable pair of a Decl and Stmt. If Stmt is not null, Decl should be its immediate parent.

This fixes the case where the wrong symbol is emitted leading to linking errors when you reference a class before defining it (GNU runtime).
