Compiling standard library with `-experimental` causes AssertionError

Compiling the bootstrapped standard library with scala2-library-bootstrapped/compile causes an AssertionError similar to #20421
if you add -experimental as a compile-time option to scalac. I think this is similar to what's happening in #20409.
