"RAS Emulation Mode" should be "RAS Mode"? #18

Does RAS Emulation Mode actually emulate anything? Wouldn't this be better called simply "RAS Mode"?

I'd argue that, when RASEMU=1, the CTR buffer is emulating a return-address stack (RAS). Returns do not actually use the addresses pushed onto it, so it is not an actual RAS.

Let me know if you disagree John, otherwise I'll close the issue at the end of this week.
