Added some updates to divider - still not working all the time. Still a bug with signals within muldiv - specificaly MultDivE being modified during Execute stage. Seems to be triggered by ahblite signal.

Fixed some divide -still bug in AHB causing InstStall to deassert and next instruction to get into divide unit. Hope to fix soon. Divide seems to work if given enough time.

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.

Merge of main with the new icache and the branch predictor. I believe there is a bug in the icache with unaligned memory access. The second part of the access is incorrectly relying on the PCF being the address of the next two bytes of the instruction. However this is not always the case as the branch predictor can get the wrong target address. The icache needs to generate the +2 address internally.
