[10] RFR(S): 8185969: PPC64: Improve VSR support to use up to 64 registers

[Doerr, Martin]

Hi Gustavo,

seems like you're preparing new VSR code :-)
Nice change, but please update the copyright messages in the modified files.

register_ppc.cpp
to_vsr(): I don't like large code for a trivial computation. I'd prefer something like "return as_VectorSRegister(encoding() + 32)".

I can sponsor this change.

Thanks and best regards,
Martin

Hi,

Could you please review this specific PPC64 change to hotspot? The aim of these changes is to allow a more complete usage of VSR. I make use of these interfaces on an instrinsic that I plan to send next but I decided to separate this change and send it first.
