Test uses PrintIdeal option which is declared as "notproduct", so, test should skip execution on product build

This looks like a testbug introduced by the fix for JDK-8146096 not being able to find the Safepoint node. [~dpochepk], could you please have a look? Please assign it back to me if it turns out to be a compiler problem.
