Returned history update to fetch.
...
- Global history only contains branches.
- Only update BHT and history on BTB hits.
- Gate off speculative update on stall or icmiss.
- Fixed bug where BHT updates were delayed a cycle.

Moved updating global history from fetch to decode.
...
- No longer update global history in fetch stage.
- Only update global history when instruction is a branch.
- Does allow for the possibility of back-to-back branches to see
slightly different histories on subsequent executions.

Bug fixes with global history register.
...
- Updated in fetch speculatively.
* Updates gated off by cpu.resp.fire().
* BTB direction factored into history update.
- All branches update the BHT.
- Each instruction carries history; index into BHT is recomputed by
passing in mem_reg_pc.

Removed RocketCoreParameters from use.
...
- The nbdache (among others?) use CoreParameters, which has nothing to do with RetireWidth requirements.
- This conflicts with other cores which uses nbdcache.
- RocketCoreParameters may be unneccessary, and the require() check can be moved deeper into Rocket.
