Description
See comments.
Problem:
Hotspot has flags which could be unavailable in different
VM versions (server vs client, product vs debug).
It complicates VM testing.

Solution:
Add new product flag -XX:+IgnoreUnrecognizedVMOptions to allow
ignore unrecognized VM options and execute a java program.
By default it is off.

EVALUATION Hotspot JVM has flags which could be unavailable in different VM versions (server vs client, product vs debug). It complicates JVM testing since JVM aborts a java program execution if there are specified options which are unavailable (unrecognized).

SUGGESTED FIX Add the flag to the test compiler/6775880/Test.java to run it with product VM (DeoptimizeALot flag is the debug flag unavailable in product VM).
