8df0d8ea63 ASTDemangler: Fix import-as-member types
When an enum is imported as an error, the imported type itself becomes
a nested type 'Code' of its wrapper type, so you get a type like
'MyError.Code'. However in the mangling grammar the type is a
child of a module and not another type.

This was tripping up TypeDecoder, which would check parent types for
validity and throw out the demangling since it looked invalid.

However since this case really is valid, just skip the whole parent
type mess when the type is imported and non-generic.

7d1a2e8339 Reinstate "Implement support for Clang's objc_runtime_visible attribute."
When a Clang-defined Objective-C class has the objc_runtime_visible
attribute, use objc_lookUpClass to get the Objective-C class object
rather than referencing the symbol directly. Also, ban subclassing of
Objective-C-runtime-visible classes as well as @objc on members of
extensions of such classes.

As a drive-by needed for this test, make
ClassDecl::getObjCRuntimeName() respect the Clang objc_runtime_name
attribute.

Fixes rdar://problem/25494454.

Fix an i32 vs. 64 issue in the IR matching for the IR generation test.

This reverts commit 09973e6956.
