This revision is now accepted and ready to land.

IMHO, it is a good idea to add a generic utility support to get a virtual live-in register for a given physical register. Otherwise, each target land-up implementing it as I had done it for AMDGPU target sometime back. Thanks for cleaning it up.  Except for my above minor comment, it is LGTM from my side unless other reviewers have any additional comments.
