cmd/compile: most recently closed type checker CLs must be cherry-picked into release branch

[griesemer]

The following three CLs need to be cherry-picked into the release branch, in the listed order:

1. CL 387977
2. CL 388294
3. CL 389594

Before doing so, we should verify that everything from the go/types, types2 side before these two CLs is already in the release branch. The go/types, types2 CL immediately before 1. is CL 388254 . If it's not present, we may need to review more closely what needs to be cherry-picked.

Thanks for filing the tracking issue for this. We'll make sure it's done before the final release, and close this issue then.

CL 388254 was submitted to the master branch before the "Go 1.19 development begins" CL 388376 dividing line, so it should make its way to release-branch.go1.18 as part of the normal release process.

Closing as duplicate of #51460 now that we have that umbrella issue.
