RFR(M): take2: 8086069: Adapt runtime calls to recent intrinsics to pass ints as long

[Lindenmaier, Goetz]

Hi,


I went back and had another look at this change.

As John proposed, I reworked it so that now the necessary sign extensions

are done in the native wrapper. These will not be subject to optimization,

but performance measurements showed no regressions.



The change also removes the shared adaptions we did before.

Could somebody please review this change?  I please need a sponsor.

Best regards,
  Goetz
