the symbol for the root meta-data.

240f2b7851 patch for two things. 
make sure objc2's nonfragile abi is enacted for Leopard too.
add -fobjc-gc-only flag to the image_info symbol.

0b0dcd987d Some initial Obj-C zero cost EH support. 
- Only handles cases with @try with no @catch blocks, and there are a
   number of problems with the implementation. Nevertheless, this is
   good enough to handled @synchronized correctly, and some other
   basic uses.

94ceb61574 Fix two @synchronized bugs found by inspection: the expression to sychronize on should only be evaluated once, and it is evaluated outside the cleanup scope. 
Also, lift SyncEnter and SyncExit up in nervous anticipation of x86-64
zero cost EH.

8de90f0a92 Obj-C non-fragile ABI: Fix types of a few globals; these were not 
creating valid LLVM structures (although they work fined).

35afdfc36e Fixed a bad ir-gen bug which caused a dejagnu test to fail. 
Now we are pretty close to be in sync with objc's classic 
abi when it comes to passing dejagnu objc executable tests.

99bed6fd21 Fixed a problem caused by foreward @class use 
which consequently caused a Seg fault. during meta-data
generation. It also addresses an issue related to
late binding of newly synthesize ivars (when we support it).

b76051534c Several cleanups: 
- rename isObjCIdType/isObjCClassType -> isObjCIdStructType/isObjCClassStructType. The previous name didn't do what you would expect.
- add back isObjCIdType/isObjCClassType to do what you would expect. Not currently used, however many of the isObjCIdStructType/isObjCClassStructType clients could be converted over time.
- move static Sema function areComparableObjCInterfaces to ASTContext (renamed to areComparableObjCPointerTypes, since it now operates on pointer types).

4d22e4975a Change construction of common ObjC functions to use CGCall 
infrastructure to construct function type.
 - For consistencty, we should probably always use this to construct
   function types, but these are absolutely necessary to ensure that
   we can emit calls to these functions.
