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.

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.
