RFR(M): 8248190: PPC: Enable Power10 system and use new byte-reverse instructions

[Doerr, Martin]

Hi Jose,

Can you replace the outdated description of PowerArchitecturePPC64 in globals_poc.hpp by something generic, please?

Please update the Copyright year in vm_version_poc.hpp.

I can‘t test the change, but it looks good to me.

Best regards,
Martin
