Fariborz Jahanian ada44a2063 Objective-C: This patch fixes a none-issuance of warning
when result type of protocol property and getter method
differ by fixing a more serious problem. When a forward
protocol declaration comes between its definition and
its use in class protocol list, the forward protocol
ast was being used in building the protocol list.

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>

John McCall 071df46743 Implement the newest status quo for method override checking. The idea now
is that we need more information to decide the exact conditions for whether
one ObjCObjectPointer is an acceptable return/parameter override for another,
so we're going to disable that entire class of warning for now.  The
"forward developement" warning category, -Wmethod-signatures, can receive
unrestricted feature work, and when we're happy with how it acts, we'll
turn it on by default.

This is a pretty conservative change, and nobody's totally content with it.

John McCall 710d2a831c Pending further discussion, re-enable warnings for Objective C
covariant/contravariant overrides and implementations, but do so under
control of a new flag (-Wno-objc-covariant-overrides, which yes does cover
contravariance too).

*At least* the covariance cases will probably be enabled by default shortly,
but that's not totally uncontroversial.
