This flag only works on the `scala3-bootstrapped/scalac` in the dotty project. It is intended for internal testing. Currently it is a bit expensive to compile the Scala 2 library TASTy. One reason in for this is that we need to use `-Ycheck:all` when compiling it to make sure that `-Yscala2-stdlib` is working properly. We only allow `scala3-bootstrapped/scalac` and not `scalac` to have this dependency for two reasons. First, we do want to be able to compile and run `scalac` command fast to reduce development testing time. Second, we do not have a stable enough version of the Scala 2 library TASTy yet. We also do not enable the Scala 2 library TASTy by default on `scala3-bootstrapped/scalac` because we still need this command to test against the current version of the library. Stability is also a concern for this version of the command.

Align with the `scala-library` and `dotty-library` nomenclature. Note that the name of the project/jar is already `scala2-library`. * `stdlib-bootstrapped` -> `scala2-library-bootstrapped` * `stdlib-bootstrapped-tasty` -> `scala2-library-tasty` * `stdlib-bootstrapped-tasty-tests` -> `scala2-library-tasty-tests` Based on #18613
