Andreas Sandberg 60290c7c2f cpu: Branch Predictor Refactoring (#455) 
Major refactoring of the branch predictor unit.
- Clearer control flow of the main branch predictor
- Remove `uncondBranch` and `btbUpdate` functions in favor
  of a common `historyUpdate` function. There is now only
  one lookup function for conditional branches and the new
  `historyUpdate` for speculative history update.
- Added a new *target provider* class.
- More expressive statistics depending on the different branch
  types.
- Cleanup the branch history management
