2aee85cb11 Flush pipeline from MEM stage
This means we no longer have to rely on the instruction behind a serializing
instruction being valid, simplifying the control.  But we have to be a
little more cautious when flusing the I$/ITLB/BTB.

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.
