Issue Description:

The following code:

struct CodableStruct : Codable {
    struct TestStruct : Codable {

    }
    let TestStruct: TestStruct
}

Consistently causes a segmentation fault in the swift binary at:

swift::MetatypeType::get(swift::Type, llvm::Optional<swift::MetatypeRepresentation>, swift::ASTContext const&)

Sample project and crash reports for swift and SourceKitService are attached. Thanks!

I believe this isn't allowed in general, but we certainly shouldn't crash!
