I started seeing a lot of situations on nv30 where fence emission wouldn't fit into the previous buffer (causing assertions). This ensures that whenever checking for space, we always leave a bit of extra room for the fence emission commands. Adjusts the nv30 and nvc0 fence emission logic to bypass the space checking as well.
