This would eliminate a lot of repetitive coding in subzero.

It's troublesome that we have to type (this) in several places but I don't see a away around it yet and it does not add to the line of code count at all to have to do this; it's just not aesthetic to me. If this idea is okay, I can make all the similar changes in the Mips Subzero port. BUG= Review URL: https://codereview.chromium.org/1661233002 . Patch from Reed Kotler <rkotlerimgtec@gmail.com>.
