- Currently CodeGen always returns a conservative value for this (-1
   or 0 depending on the context).

Highlights...

- 4 new AST nodes, BlockExpr, BlockStmtExpr, BlockExprExpr, BlockDeclRefExpr.
- Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt().

Next steps...

- hack Sema::ActOnIdentifierExpr() to deal with block decl refs.
- add attribute handler for byref decls.
- add test cases.

 - Allow any Objective-C object types to devolve to type id in a ?:
   expression. This matches gcc behavior more closely.

 - Now also searches for correct setter method.
 - There are still some issues regarding validation of the setter
   method and access of read-only properties.

anywhere near correct in terms of missing cases and missing 
diagnostics, but it's good enough to handle the uses in the 
Linux system headers, which are currently a constant pain for compiling 
applications on Linux.

type-checking pointer subtraction; if the canonical types aren't used,
the qualifiers won't always get stripped off correctly.

I'll try to come up with a correct fix for the testcase sometime soon.

- warn about nonnull being applied to functions with no pointer arguments
- continue processing argument list in the attribute when we encounter a non-pointer parameter being marked as nonnull
- when no argument list is specified, only mark pointers as nonnull.  This fixes PR 2732 and radar 6188814.

 - Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
   favor of just result type and selector. Necessary so it can be
   reused in situations where we don't want to cons up an
   ObjCMessageExpr.
 - Update aggregate binary assignment to know about special property
   ref lvalues.
 - Add CodeGenFunction::EmitCallArg overload which takes an already
   emitted rvalue.

Add CodeGenFunction::StoreComplexIntoAddr.

Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.

Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

This commit adds the declaration syntax (and associated type).

 - It is not clear that this is the right approach, but this is at
   least consistent with how interfaces are handled.

 - This means NeXT now emits the correct metadata for properties in
   protocols.

 - This currently introduces a spurious warning involving inherited
   properties in protocols or categories; however, it also fixes some
   situations where we were failing to emit a warning. I will scrub
   this code tomorrow and fix this issue as well as number of other
   missed warnings / error situations that appear to exist.

 - Add ObjCMethodDecl::createImplicitParams.
 - Remove ObjCMethodDecl::set{Self,Cmd}Decl
 - Remove Sema::CreateImplicitParameter

No (intended) functionality change.

 - Change enum name to Kind.
 - Change enum constants to English strings.

Also, fix getPropertyImplementation (which probably should be renamed)

of RHSs to id type instead of void* if either has Objective-C object
type.
 - This ensures the result can still be used in normal places an
   object can be used, like a message send.

Add implicit conversions for ?: applied to qualified id types to
ensure that the RHSs are compatible. 
 - This prevents a codegen crash (creating invalid PHI nodes).
 - Again, this relates to the fact that qualified id types have no
   canonical types.
 - Note that the implicit type casted to is incorrect, however this
   doesn't currently cause problems because of the flexibility of the
   id type.

Test cases for above.

which made function type compatibility checking a bit more strict.

Eventually, we should check whether we can evaluate an expression 
using Expr::tryEvaluate, and this codepath should be tightened to only 
handle standard-compliant cases.

-The Parser calls a new "ActOnCXXTypeConstructExpr" action.
-Sema, depending on the type and expressions number:
   -If the type is a class, it will treat it as a class constructor. [TODO]
   -If there's only one expression (i.e. "int(0.5)" ), creates a new "CXXFunctionalCastExpr" Expr node
   -If there are no expressions (i.e "int()" ), creates a new "CXXZeroInitValueExpr" Expr node.

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.

 - UsualUnaryConversions takes an Expr *& and may modify its argument,
   this broke when it was refactored into Sema::CheckCastTypes. This
   meant that we were missing implicit casts in some places.
 - Seems pretty sad that this got through our tests.

This fixes an ownership issue where FieldDecls could be owned both by an ObjCInterfaceDecl and a RecordDecl.

Add ExplicitCastExpr to replace the current CastExpr, and have ImplicitCastExpr and ExplicitCastExpr derive from a common base class (CastExpr):

Expr
  -> CastExpr
     -> ExplicitCastExpr
     -> ImplicitCastExpr
