Steve Naroff 8e6aee5821 Remove a bunch of FIXME's related to ObjC type checking. 
- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext.
- Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible(). 
- Tweak several test cases to accommodate the new/improved type checking.

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc. 
Tests and drivers updated, still need to shuffle dirs.

Steve Naroff 3f49feeed5 Finish up some fixes related to <rdar://problem/6497631> Message lookup is sometimes different than gcc's. 
- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

Fariborz Jahanian 9a8e759b4f Implement an important missing warning when a selector 
is searched for in the global pool. It already uncovered 
a clang bug in message selection.

Steve Naroff 8afa98916a Downgrade incompatibilities with objc qualified types (e.g. id <P>) to warnings. 
Note: One day, we should consider moving the actual diags to ObjCQualifiedIdTypesAreCompatible(), since it has more information on the actual problem. GCC currently emits slightly more instructive errors for some cases involving protocols. I added a FIXME to the code.

Daniel Dunbar de1ec9cdcd Improve type-checking of ?: for Objective-C types. 
- Allow any Objective-C object types to devolve to type id in a ?:
   expression. This matches gcc behavior more closely.

Chris Lattner 89026888ef move all objc sema tests into a new SemaObjC directory. Next step is to 
remove the objc- prefix from the tests that use it.
