Yes, you need _WIN64 set for windows-aarch64 even if you comment out or remove the isTargetCpuBits block.

My concern with just changing just the .ad file is there are other uses of #ifdef _WIN64 in x86 .hpp header files that adlc files might include directly or indirectly.

To me JDK-8256205 just looks like a refactoring.  I don't see how it would change the calling convention.
