Followup to #5020.

Testing that our benchmark program don't need to link against the compiler.
Warning: This might make performance incomparable with earlier (similarly to
other current changes.

The classpath is intended for type checking, not for compiler run-time.
Thus, they should be passed as compiler options, not JVM options.

It works before because the compiler makes bootstrap classpath
available for type checking. However, we can no longer use bootstrap
classpath after Java 9 support (scala#3138).
