Changes from before 4cd1a0be7688 to after 4cd1a0be7688
These changes all look fine to me with a couple exceptions. Some of the
shaders have a hunk at the beginning like:

I haven't looked at it to closely, but this seems suspicious. In this case,
g77 was previously the result of the CMP instruction. It seems unlikely that
g30 will have a value that could be valid for any remaining uses of g77.</pre>
