Corrected a number of bugs in the branch predictor.
...
Added performance counters to individually track
branches; jumps, jump register, jal, and jalr; return.
jump and jump register are special cases of jal and jalr.
Similarlly return is a special case of jalr.
Also added counters to track if the branch direction was wrong,
btb target wrong, or the ras target was wrong.
Finally added one more counter to track if the BP incorrectly predicts
a non-cfi instruction.

Fixed bugs with the csr interacting with StallW. StallW is required to pervent updating a csr. Now have a working branch predictor and performance counters to track the number of commited branches and mispredictions.
