[WIP][DO-NOT-MERGE] Test the -Yrepl-class-based changes

[dwijnand]

Hi! This PR is to test the change to the scala compiler's -Yrepl-class-based option (which the Spark REPL uses) that landed in scala/scala#8712.

I don't expect it to be merged. :)

I tested this locally with:

./build/mvn -P scala-integration -Dscala.version=2.12.11-bin-4c726db -pl :spark-repl_2.12 -Dtest=none -DwildcardSuites='org.apache.spark.repl.ReplSuite,org.apache.spark.repl.SingletonReplSuite,org.apache.spark.repl.ExecutorClassLoaderSuite' test

and that subset passed for me. I'm interested to see if those or any other tests fail in CI.

[dwijnand]

Could anyone tell me in which check tests like ReplSuite are run, please?

[srowen]

Jenkins test this please

[srowen]

@dwijnand It should run all tests as the parent POM changed, including ReplSuite.
