RFR(XS): 8193310: [MVT] Graph for 'TestMinimalValueTypes::test7' fails IR verification

[Tobias Hartmann]

Hi,

please review the following patch:
https://bugs.openjdk.java.net/browse/JDK-8193310
http://cr.openjdk.java.net/~thartmann/8193310/webrev.00/

The test fails with -XX:CompileThreshold=100 because C2 emits fast throws for NullPointerExceptions which are not
detected by IR verification. I've disabled fast throw via -XX:-OmitStackTraceInFastThrow in case IR verification is enabled.

All tests pass.

Thanks,
Tobias
