1) Enforce C99 6.7.3p2: "Types other than pointer types derived from
...
object or incomplete types shall not be restrict-qualified."
2) Warn about qualifiers on function types: C99 6.7.3p8: "If the
specification of a function type includes any type qualifiers, the
behavior is undefined."
3) Implement restrict on C++ references.
4) fix some locations for various C++ reference diagnostics.

Fix several bugs in array -> pointer decomposition.
...
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.
Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.
Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").
This adds an ASTContext::getArrayDecayedType member that handles the
non-trivial logic for this seemingly simple operation.

Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl).

- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.

- Some minor indentation changes.

Fix objc ivar lookup. Ivar lookup should occur between lookup
of method-local values and lookup of globals. Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.
Two todo's left:
1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
in the AST. This is a hack.
2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
not correctly handle typedefs and enum constants yet.

some cleanups on top of David's patch. There are still two
...
remaining open issues I've communicated to him:
1) self can be assigned to, and his patch didn't handle it correctly.
2) CollectObjCIvarTypes is N^2 (because each subclass reprocesses
all parent class ivars) and flattens classes. If A derives from B,
and both have an int, I'd expect to get { {i32}, i32}, not { i32, i32}.
