This fixes use of alloca on 64-bit systems.

the volatile flag.  Places which need some further attention are marked 
with FIXMEs.

isn't guaranteed to exist. This fixes a crash with conflicting typedefs
coming from stdin.

This also fixes the crash in PR2406, but doesn't completely fix the 
issue; it appears there's something strange about the physical location 
for the definition of int64_t in stdlib.h.

-ScopedDecls get chained to their DeclContext.
-DeclContext's DeclChain replaces FunctionDecl's DeclChain and EnumDecl's ElementList.

  Added TagKind enum.
  Added getTagKind() method.
  Added convenience methods: isEnum(), isStruct(), isUnion(), isClass().
-RecordDecl/CXXRecordDecl::Create() accept a TagKind enum instead of a DeclKind one.

pointer cast hack currently in isIntegerConstantExpr 
(in lib/AST/Expr.cpp).  Also removes an odd test that even gcc doesn't accept.

The reason the pointer cast hack is relevant here is that it makes Sema 
end up misinterpreting the relevant expression as a null pointer constant.

The reason for this patch is that I plan to remove the pointer cast hack 
sometime soon because it causes strange issues, especially in its 
current form; see my recent email to cfe-dev
"[PATCH] add constant expression evaluation to the AST and fix PR2413".

type; this isn't explicitly stated in the standard, but it doesn't 
really make sense for them to have an effect here.  Fixes the included 
testcase, sent to me by Steve Naroff.

This fix just makes sure to construct the global with the appropriate 
type, and fixes up the one user this affects to compensate.

reported on cfe-dev by Cédric Venet.

Note that I seriously doubt that this perticular construct is useful, 
though: it's a pointer in an alternate address space pointing into 
unqualified address space.

Implement "Destroy" and destructor for ObjCClassDecl, allowing us to reclaim its memory and the memory of the Decls it owns.

ObjCPropertyDecls, have TranslationUnit destroy ObjCPropertyDecls. This is a
horrible hack, and must be removed eventually.

llvm-svn: 52051

have Destroy methods of ObjcMethodDecl and ObjCInterfaceDecl which recursively
destroy their owned Decls and Stmts.  There are a few cases where it is not
clear what to do (FIXMEs included in the patch).

- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

llvm-svn: 52005

In addition to fixing the crasher, this commit fixes further improves property lookup (by searching protocols of qualified interfaces..."NSObject <prot>").
