RFR (M) 8209946 [TESTBUG] CDS tests should use "@run driver"

[Jiangli Zhou]

Hi Ioi,

The change seems ok. Could you please give some details on the benefit 
of using @run driver? Could you also please verify it does not affect 
the jtreg options passed to the dump & run processes for each individual 
test?

Thanks,

Jiangli
