RFR: 8184017: [MVT] Support Q-types in MHs.insertArguments()

[Vladimir Ivanov]

Thanks, Maurizio & Paul.

Yes, all tests in jdk/test/valhalla/mvt pass.

I decided to write a dedicated unit test and here's an updated version:
   http://cr.openjdk.java.net/~vlivanov/valhalla/8184017/webrev.01/

Also, added explicit null check to align the behavior on MVTs with 
primitives.

Best regards,
Vladimir Ivanov
