When handling a type declaration like: ``` type B A ``` unified IR has been writing out that B's underlying type is A, rather than the underlying type of A. This is a bit awkward to implement and adds complexity to importers, who need to handle resolving the underlying type themselves. But it was necessary to handle when A was declared like: ``` //go:notinheap type A int ``` Because we expected A's not-in-heap'ness to be conferred to B, which required knowing that A was on the path from B to its actual underlying type int. However, since #46731 was accepted, we no longer need to support this case. Instead we can write out B's actual underlying type. One stumbling point though is the existing code for exporting interfaces doesn't work for the underlying type of `comparable`, which is now needed to implement `type C comparable`. As a bit of a hack, we we instead export its underlying type as `interface{ comparable }`. Fixes #54512.
