RFR(XL/M) : 8178788: wrap JCStress test suite as jtreg tests

[Stuart Monteith]

Hello,
  I've spent some time on this,  and I have to admit that I'm stumped. I
get exactly the same errors on x86 on jdk10/hs and jdk10/jdk10 with arecent
build of JTReg and JT_HOME set appropriately.

Are there any pointers on how this is supposed to be run?

Thanks,
   Stuart
