fea31d2167 Significant changes and fixes to BTB for superscalar fetch. 
- BTBUpdate only occurs on mispredicts now.
   - RASUpdate broken out from BTBUpdate (allows RASUpdate to be performed in
      Decode).
   - Added optional 2nd CAM port to BTB for updates (for when updates to the
      BTB may occur out-of-order).
   - Fixed resp.mask bit logic.

- Global history only contains branches.
   - Only update BHT and history on BTB hits.

   - Fixed bug where BHT updates were delayed a cycle.
