[PATCH] D48638: [Sparc] Add support for the cycle counter available in GR740

I wonder if we perhaps shouldn't've modeled the ASR registers as registers at all (other than Y -- it's "special"). That seems to be what other targets do with their MSRs. Not sure if it really matters...

Anyways, having it be marked reserved seems correct.  It may be simpler to just always mark ASR1-31 as reserved, though?
