scoped options usage in hsail

[Deneau, Tom]

I have posted a small webrev for how we use the scoped options feature in hsail



http://cr.openjdk.java.net/~tdeneau/graal-webrevs/webrev-scoped-options/webrev/



The previous way of using scoped options only forced new options on a few tests.  While this was enough to make the existing java 7 junit tests pass, in reality we want to force the options on all tests (this is how we were running things here).



So I pushed the scoped options overrides down into GraalKernelTester.java which all tests go thru.



The assumeTrue(aggressiveInliingEnabled) assertions then had to move one layer down, to the runTest routine.
