RFR(M): 8144466: ppc64: fix argument passing through opto stubs.

[Doerr, Martin]

Hi Vladimir,

C1 does the int to long conversions in the platform code. I didn't find any missing conversion in the C1 code.
The only C1 issue with respect to runtime calls is 8143817 for which I'll send out another email.

Best regards,
  Martin

Looks fine. Do you need to do anything for C1 which you have now?

Thanks,
Vladimir
