This test renames a receiver, type parameter, parameter or result var
whose name matches a package-level decl. Prior to go1.22, this used to
cause a spurious shadowing error because of an edge case in the
behavior of types.Scope for function parameters and results.

This is a regression test for issue #60752, a bug in the type checker.
