Does this give us parity between Linux/Windows at this point or are there others that are still missing on Windows that Linux currently handles?

ARM64IntrinsicConstants_Rcpc2 and ARM64IntrinsicConstants_Rdm are still missing and I didn't see their equivalent yet on windows side.

I don't see an entry of LRCPC2 in that. It just has LRCPC that is mapped to 45.

Yes, it's not LRCPC2. Not a big deal though, it's just a minor optimization on top of RCPC1
