cpu: remove local/globalHistoryBits params from branch pred
having separate params for the local/globalHistoryBits and the local/globalPredictorSize can lead to inconsistencies if they are not carefully set. this patch dervies the number of bits necessary to index into the local/global predictors based on their size. the value of the localHistoryTableSize for the ARM O3 CPU has been increased to 1024 from 64, which is more accurate for an A15 based on some correlation against A15 hardware.
