r300/compiler: Implement the texture semaphore
The texture semaphore allows for prefetching of texture data. On my
RV515, this increases the FPS of Lightsmark by 33% (This is with the
reg_rename pass enabled, which is enabled in the next commit).
There is a new env variable now called RADEON_TEX_GROUP, which allows
you to specify the maximum number of texture lookups to do at once.
The default is 8, but different values could produce better results
for various application / card combinations.
