llvmpipe: still more bin code reorganization
...
Move tiles_x,y fields from setup state into bin state.
Move more bin-adding commands into lp_bin.[ch].

llvmpipe: reorganization of binning data structions and funtions
...
New lp_bins struct contains all bin information.
More move bin-related code into lp_bin.[ch]
Use new/updated bin-access functions to hide implementation details.
The result is more/cleaner separation between the setup and rast components.
This will make double-buffering of the bins easier, etc.

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.

Now tri-z.c, gears.c, etc look basically right but there's still some
cracks in triangle rasterization.
