* fix a bug of wrongly discarding some new bits to be xored
* ghr should be longer in default config to avoid falsely overriding
* move TageBanks to top, and fix SC folded history config

* fix a bug of wrongly discarding some new bits to be xored
* ghr should be longer in default config to avoid falsely overriding
* move TageBanks to top, and fix SC folded history config

bpu: bring folded history into use, and use previous ghr to do difftest; move tage and ittage config to top

* use compressed info to do redirects
* implement folded history class

previously we may use random data from ftq meta sram, and now we fixed this issue

* rename Roq to Rob

* remove trailing whitespaces

* remove unused parameters

* modify UBitPeriod to one-eights of the previous value to adapt
  to nRows enlarged by eight times
* fix a bug assigning sc update mask

* fix a bug when establishing new ftb entry with a jalr
* use ftb hit signal instead of ubtb to assign entry_hit_status
* move always taken logic to ftb
