Webrev fix for -UseHSAILDeoptimization

[Caspole, Eric]

Hi everybody,
I put a new webrev here -

 http://cr.openjdk.java.net/~ecaspole/fix_deopt_off/webrev/

This fixes problems where recent changes hade made it so -XX:-UseHSAILDeoptimization was not having the intended effect. With this patch the codegen is correct with -XX:-UseHSAILDeoptimization  and the tests have been updated so the hsail tests run clean with or without -XX:-UseHSAILDeoptimization. This passed "mx gate." Note +UseHSAILDeoptimization is still the default for regular Java compatibility.

Let me know your comments,
Thanks,
Eric
