lots of debugging of predication, found other errors

lots of stuff here:
* changed sv reg and pred entry layout to make them a bit more
  human-readable: put the key and idx on byte-boundaries
* bug in SV REG setting (getting int table instead of fp one, twice)
* bug(s) in SV PRED table setting (zeroing the reg tables, using idx not
  key and more)
* stop lookup of predication if the *REGISTER* entry is inactive
  (but not if it is a scalar, because scalar predication is ok)
  this was the final piece of the puzzle that got predication working
* added a useful macro for creating SV REG and PRED CAM table entries

predication now working including zeroing

6 years agoadd sv support for zeroing predication in dest register

add sv support for zeroing predication in dest register

bit of a major rework:

* access to the "unpredicated" (non-zero-hacked) register was needed
* therefore all rd/rs1-3/rvc_xxx functions had to have _ variants
* the underscored variants are not predicated
* this in turn meant that the offset for each register was wrong
  as it is incremented *after* being checked
* therefore a newoffs had to be added
* and the reset_cache function copies the newoffs values

bit of a mess but it works: this is a state machine after all...
