This fixes several issues in C2 with -XX:-ScalarizeInlineTypes and improves robustness of the tests to be able to run with more stress options. We still need a good heuristic to decide when **not** to scalarize inline types (for example, if there are too many (oop) fields), this will be addressed by [JDK-8215479](https://bugs.openjdk.java.net/browse/JDK-8215479).
Best regards,
Tobias
