Could someone please have a look at this change?
I had a look whether I can push the functionality down to make_runtime_call().
This would simplify matters a lot. But as the TypeFunc is hashed, I can not
change it any more in make_runtime_call().
@aarch-people: I saw you have CCallingConventionRequiresIntsAsLongs set.
Could you please check whether this breaks your intinsics, e.g., multiplyToLen?
(We assure in sharedRuntime_ppc.cpp, c_calling_convention() that no INT types
end up there.)

Subject: RFR(M): 8086069: Adapt runtime calls to recent intrinsics to pass ints as long
we are working on porting the recently* added intrinsics to PPC. As these use
runtime calls, the calls must obey to the platform ABI, which requires that ints
are passed as longs.
We made a similar change in "8024342: PPC64 (part 111): Support for C calling
conventions that require 64-bit ints." It adapts the calls if
CCallingConventionRequiresIntsAsLongs is set.
This change adapts the calls to multiplyToLen, CRC32, AES, SHA accordingly.
Please review this change. I please need a sponsor.
* i.e., added after making our initial port
