// Test a corner case of LUB coercion. In this case, one arm of the
// match requires a deref coercion and the other doesn't, and there
// is an extra `&` on the `rc`. We want to be sure that the lifetime
// assigned to this `&rc` value is not `'a` but something smaller.  In
// other words, the type from `rc` is `&'a Rc<String>` and the type
// from `&rc` should be `&'x &'a Rc<String>`, where `'x` is something
// small.
