Patrick Beard acfbe9e1f2 Added a new attribute, objc_root_class, which informs the compiler when a root class is intentionally declared.
The warning this inhibits, -Wobjc-root-class, is opt-in for now. However, all clang unit tests that would trigger
the warning have been updated to use -Wno-objc-root-class. <rdar://problem/7446698>

Douglas Gregor dc9166c8e1 Keep track of all declarations of an Objective-C class (both forward
declarations and definitions) as ObjCInterfaceDecls within the same
redeclaration chain. This new representation matches what we do for
C/C++ variables/functions/classes/templates/etc., and makes it
possible to answer the query "where are all of the declarations of
this class?"

Douglas Gregor 4123a86fae Use Sema::RequireCompleteType to check for the completeness of
Objective-C classes. This has two purposes: to consistently provide
"forward declaration here" notes when we hit an incomplete type, and
to give LLDB a chance to complete the type.

RequireCompleteType bits from Sean Callanan!

Fariborz Jahanian 3ee91fad90 When forming a cycle in objc's inheritance hierarchy,
diagnose it properly and don't throw clang into an
infinit loop. // rdar://9653341

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Fariborz Jahanian 0d451813f9 a forward class declaration matching a typedef name of a class
refers to the underlying class.
This is radar 6859726. Steve, please read the radar for my rational.

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

Chris Lattner e6447ef989 make some objc redefinition warnings more consistent: call definitions
"definitions", not declarations.  Point out the location of the 
original definition.

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.
