llvmpipe: bin state-change commands
...
Previously, each triangle had a pointer to the state to use for shading.
Now we insert state-change commands into the bins. When we execute one
of those commands we just update a 'current state' pointer and use that
pointer when calling the jit shader.
When inserting state-change commands into a bin we check if the previous
command was also a state-change command and simply replace it. This
avoids accumulating useless/redundant state-change commands.

This matches the convention used by the recursive rasterizer.
Also fixed assorted typos, comments, etc.
Now tri-z.c, gears.c, etc look basically right but there's still some
cracks in triangle rasterization.
