  - If a declaration is an invalid redeclaration of an existing name,
    complain about the invalid redeclaration then avoid adding it to
    the AST (we can still parse the definition or initializer, if any).
  - If the declaration is invalid but there is no prior declaration
    with that name, introduce the invalid declaration into the AST
    (for later error recovery).
  - If the declaration is an invalid redeclaration of a builtin that
    starts with __builtin_, we produce an error and drop the
    redeclaration. If it is an invalid redeclaration of a library
    builtin (e.g., malloc, printf), warn (don't error!) and drop the
    redeclaration.

If a user attempts to define a builtin, produce an error and (if it's
a library builtin like malloc) suggest -ffreestanding.

This addresses <rdar://problem/6097585> and PR2892. However, PR3588 is
still going to cause some problems when builtins are redeclared
without a prototype.

castToDeclContext/castFromDeclContext are only required to be included in the class of decls that directly derive from DeclContext.
Their subclasses don't need them.

llvm-svn: 64632

castToDeclContext/castFromDeclContext are not meant to be used directly; they are used indirectly by cast/dyn_cast.
All Decl <-> DeclContext casting should be done through cast/dyn_cast.

llvm-svn: 64631

DeclContext had its "casting machinery" inside the class definition so that if a new declaration context Decl appeared, the necessary changes
would be in one place. Since, now, only DeclNodes.def needs to be modified, move things out-of-line and simplify the DeclContext class.

llvm-svn: 64630

-In DeclNodes.def, only mark as DeclContexts the top classes that directly derive from DeclContext. If the Decl has subclasses,
 it should be marked with DECL_CONTEXT_BASE.

-Use DeclNodes.def to automate the DeclContext::classof and DeclContext::CastTo definitions.
