RFR: 8296030: compiler/c2/irTests/TestVectorizeTypeConversion.java fails with release VMs after JDK-8291781

[Jie Fu]

Hi all,

compiler/c2/irTests/TestVectorizeTypeConversion.java fails with release VMs due to 'SuperWordRTDepCheck' is develop and is available only in debug version of VM.
To fix it, `-XX:+IgnoreUnrecognizedVMOptions` is added in the test.

Thanks.
Best regards,
Jie
