isa: clean up register constants
Clean up and add some consistency to the *_Base_DepTag
constants as well as some related register constants:
- Get rid of NumMiscArchRegs, TotalArchRegs, and TotalDataRegs
since they're never used and not always defined
- Set FP_Base_DepTag = NumIntRegs when possible (i.e.,
every case except x86)
- Set Ctrl_Base_DepTag = FP_Base_DepTag + NumFloatRegs
(this was true before, but wasn't always expressed
that way)
- Drastically reduce the number of arbitrary constants
appearing in these calculations
