If a swift_name attribute’s context referred to the same declaration it was attached to, or a different declaration whose own swift_name referred to the current one, we would recurse infinitely and eventually overflow the stack. This commit makes us instead detect the cycle, diagnose it with a warning, and drop the affected declaration. Fixes rdar://79370809.
