[Mesa-dev] [PATCH 00/19] Remove all uses of the register mask

These patches show that sometimes we used it even when we didn't have to, and the few cases that are valid can be handled separately without much effort anyway. The majority of registers don't need this feature.

I've looked over this and I've wanted to do something like this since
I first ran callgrind on r600g, reducing the CPU overhead here is a
good plan.
