Compiler crash on using internal import (AccessLevelOnImport feature)

Description

When I start using AccessLevelOnImport and do public / internal import the compiler crash time to time. It really depends on project structure and some times disappears when I restructure dependencies.

Reproduction

Small project reproducing the crash: https://github.com/ordo-one/external-reproducers/tree/main/swift/swift-crash-on-access-level-import.

If .enableExperimentalFeature("AccessLevelOnImport") is removed and internal import is replaced to @_implementationOnly import, then crash is gone.
