        Description

        It severely hoards the parallelism of CTW tests, accounting for a very large single-job trail after everything else is compiled. Following the precedent of splitting java_base.java and java_desktop.java into two halves (JDK-8202169), we should do the same for jdk_localedata.java.

        With JDK-8238247 applied and this patch :
          https://cr.openjdk.java.net/~shade/8238591/webrev.01/

        $ time CONF=linux-x86_64-server-fastdebug make run-test TEST=applications/ctw/modules/
