Cannot pass jvm parameters to dotr

See original GitHub issue

When calling dotr (without launching the repl) we cannot pass JVM arguments such as -Xmx512. We should probably support the -JXmx512 notation the dotc supports. All flags starting with -J should be passed to the JVM without the J.

dotr [-repl|-run] <jvmopt>* [<Main> <main-args>*]

<jvmopt> = -classpath <some-classpath>
         | -J<jvm-option>

Run the REPL if -repl is set or if -run is not set and [<Main> <main-args>*] not is present. Run the app if -run is set or [<Main> <main-args>*] is present.

Running should call java <jvmopt-transformed>* <Main> <main-args>* where jvmopt-transformed removes the J from -J<jvm-option> and merges the classpaths toghether. -classpath and the dotty library classpath (currently in the script) in that order.

If several -classpath are found in <jvmopt>* then keep the last one. Maybe emit a warning.

For the REPL keep -classpath as is.
