371b8fb4c3 Fix <rdar://problem/6640991> Exception handling executes wrong clause (Daniel, please verify). 
Also necessary to fix:

<rdar://problem/6632061> [sema] non object types should not be allowed in @catch statements
<rdar://problem/6252237> [sema] qualified id should be disallowed in @catch statements

76b7acc49f First cut at zero-cost EH support. 
- Still manually generates the EH code; the parts related to cleanup
   need to be integrated into the cleanup stack (for proper
   interaction with VLAs, etc.).

 - Some differences vs gcc in corner cases; I believe our behavior is
   correct but need to verify/file bugs vs gcc.

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.

35afdfc36e Fixed a bad ir-gen bug which caused a dejagnu test to fail.

abi when it comes to passing dejagnu objc executable tests.

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.

   we can emit calls to these functions.
