Mark a bunch of VFPU ops that eat prefixes

I suppose they all do per interpreter, just wanting to verify.

This is enough to get Wipeout Pure and Fat Princess running in game with the startDefaultPrefixes flag still true.  Int_VecDo3 isn't being called at all anymore, as such, and the improvement seems noticeable for Fat Princess.

A bunch of the ops hit failures otherwise, not matching basic tests... and vcmp seems incomplete.  But those conditions didn't seem to be hit by the video which still doesn't work.

I also changed the mask on matrices to log, it seems like it (sometimes) uses it for the last column, but it probably depends on instruction...
