This patch tries to be smarter when figuring out optimal jvm args for

For this to work properly, two patches to the sjavac src langtools are
also needed, but they will be handled in separate bugs and code reviews.
can't really comment but does sjavac really need to mess with these:
!
ADD_JVM_ARG_IF_OK([-XX:PermSize=32m],SJAVAC_SERVER_JAVA,[$SJAVAC_SERVER_JAVA])
!
ADD_JVM_ARG_IF_OK([-XX:MaxPermSize=160m],SJAVAC_SERVER_JAVA,[$SJAVAC_SERVER_JAVA])
!
ADD_JVM_ARG_IF_OK([-XX:ThreadStackSize=$STACK_SIZE],SJAVAC_SERVER_JAVA,[$SJAVAC_SERVER_JAVA])
I honestly don't know. Fredrik added those way back in the beginning
when Hotspot had trouble running the javac server. I know he got much
better performance with JRockit as the server compiler runtime at the
time. I will remove them and run another jprt job and see if something
nasty happens. Getting rid of it would be nice.
