testing compatibility. This is necessary for some constructs, like merging
redeclarations.
Also, there are some ObjC changes to make sure that
typesAreCompatible(a,b) == typesAreCompatible(b,a). I don't have any
ObjC code beyond the testsuite, so please tell me if there are any cases
where this doesn't behave as expected.

- Kill unnecessary #includes in .cpp files. This is an automatic
sweep so some things removed are actually used, but happen to be
included by a previous header. I tried to get rid of the obvious
examples and this was the easiest way to trim the #includes in one
fell swoop.
- We now return to regularly scheduled development.

- Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
- Moved Sema::getCurMethodDecl() out of line (dependent on
ObjCMethodDecl via dyn_cast).

Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.

- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.
Still some more work to do (forthcoming)...

scimark2 on Darwin.
- Added Sema support for asm-label on variables, which I forgot before.
- Update CodeGen to use GlobalDeclMap to determine if static Decls
require emission (instead of LLVM module name lookup). Important
since the Decl name and the LLVM module name can differ.

- ActOnDeclarator now takes an additional parameter which is the
AsmLabel if used. Its unfortunate that this bubbles up this high,
but we cannot just lump it in as an attribute without mistakenly
*accepting* it as an attribute.
- The actual asm-label itself is, however, encoded as an AsmLabelAttr
on the FunctionDecl.
- Slightly improved parser error recovery on malformed asm-labels.
- CodeGen support still missing...

move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).
Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

This change also fixes a subtle bug where the access control of an ivar would be initialized to garbage if we didn't have an explicit visibility specifier (e.g., @private).

of a specific smallvector size.
Fix protocol lists to pass down proper location info, so we get diagnostics
like this:
t.m:3:35: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^
instead of this:
t.m:3:44: error: cannot find protocol definition for 'NSCopying', referenced by 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
^
Add a new IdentifierLocPair typedef which is just a pair<IdentifierInfo*, SourceLocation>

- Make sure ObjCIvarDecl propagates the bitfield width.
- RewriteObjC::SynthesizeIvarOffsetComputation(): Avoid using the __OFFSETOF__ mumbo jumbo for bitfields (since it isn't legal C). This fixes <rdar://problem/5986079> clang ObjC rewriter: bitfields and ivar access don't mix.

converted, breaking the case where one declspec was shared by multiple
declarators.

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.

-DeclContext's DeclChain replaces FunctionDecl's DeclChain and EnumDecl's ElementList.

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".
