alan: two comments on this:
1. shouldnt this go with the earlier patch?
2. i agree with renaming the names of the register to reflect the when
   all of those registers got first introduced... however, considering
   we only support GuC on Gen12 and beyond (we do have select CI-tests
   that enable GuC on Gen9 but not on Gen8 and before), should we also
   change the comments? I think the comment should reflect the usage
   not just follow the same name of the registe #define - else why even
   add the comments. (please apply this same comment for gen8_vd_inst_regs,
   gen8_vec_inst_regs and gen8_blt_inst_regs).
alternatively, we could keep those GEN8+ comments above the list but maybe
add just one comment in the default list - see below.

alan: perhaps add a comment that we really don't support any of this
on anything below Gen9?
