Request for reviews (XS): 6886353: For DeoptimizeALot, JTreg tests should "IgnoreUnrecognizedVMOptions on a product build

[Changpeng Fang]

 http://cr.openjdk.java.net/~cfang/6886353/webrev.00/

Problem:
JTreg tests on a product build will fail if the regression tests use 
DeoptimizeALot ( a debug option)

Solution:
Add -XX:+IgnoreUnrecognizedVMOptions  so that the product build  tests  
can ignore  DeoptimizeALot


Thanks,

Changpeng
