681b43f398 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.

f917810061 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.

868e747656 Factored out Rocket specifics from CoreParameters 
- Added new RocketCoreParameters
   - Other cores using Rocket as a library will no longer conflict against
      Rocket's requires().

fefa560017 Change addons subproject to use .addons-dont-touch directory instead of addons 
This hides the directory name under standard invocations of ls and thus avoids confusing the user with extra directory names.

69d765744c Adjustments to the build structure (see below) 
All 'addon' subprojects now have their sources aggregated into the addons subproject. This is done via a source copy (so that sbt will only rebuild sources that actually changed). To prevent caching issues the addons/src directory is CLEARED and then refilled every time addons is compiled. Thus, it is CRUCIAL NO SOURCES ARE MANUALLY ADDED TO addons/src AS THEY WILL BE WIPED BY addons/prepare. Due to sbt source caching, sbt will still be able to tell which sources have changed. (Strangely, sbt would not cache sources in extra unmanaged source directories and thus would always recompile them.) Also, cleaned up project/build.scala a bit to remove some warnings: Added import scala.language/postFixOps (so make! at the bottom no longer errors) and .toURI.toURL (as straight .toURL has been deprecated by the java standard library).
