Basic option processing is still broken for REPL

[som-snytt]

Compiler version

3.1.0-RC1-bin-SNAPSHOT

Minimized code

✗ ./bin/scala -source 3.0-migration
Exception in thread "main" java.nio.file.NoSuchFileException: -source

Output

// As shown.

Expectation

Processing command line options for the compiler, with additional REPL-specific options.

Did it work well for Scala2 or before changing the scala runner from shell script to scala script (#13081)? I know why it fails and have an idea of how to fix it

A workaround: add -repl as a last arg works i some situations.
