Implement getSubRegIndex as a linear search on the SubRegTable instead of using a big switch.
- The search bounds are constant, in the worst case (ARM target) it will scan over 30 uint16_ts.
- This method isn't very hot, I had problems finding a testcase where it's called more than a dozen of times (no perf impact).
