Description
The PPC ABI requires that ints are passed as correct long values.
"8024342: PPC64 (part 111): Support for C calling conventions that require 64-bit ints."
adapted runtime calls issued by C2 accordingly.

Intinsics for multiplyToLen, CRC32, AES and SHA use runtime calls and thus must
obey to the ABI. 

This change adapts the calls to the new intrinsics using the mechanism introduced in 8024324.
