VIF/VU: Fixes for Everblue and Hitman 2 from r5404, details below.  Savestate bump needed, sorry. Also fixed a copy/paste bug i noticed along the way in vif0FBRST.

Everblue: Slightly messy fix, not as nice as id hope, but it seems to work, we need to remember VU programs written to the VU so we can check if an unpack is modifying it.  This retains the behaviour of the Snowblind engines whilst fixing everblue.

Hitman 2: Our vif0/1VUFinish() routing which works in conjunction with the delays wasn't paying attention to if the VIF was stalled or not and reran it before the game wanted it to, now fixed.
