llvmpipe: avoid generating tri_16 for tris which extend past tile bounds
Don't trim triangle bounding box to scissor/draw-region until after the logic for emitting tri_16. Don't generate tri_16 commands for triangles with untrimmed bounding boxes outside the current tile. This is important as the tri-16 itself can extend past tile bounds and we don't want to add code to it to check against tile bounds (slow) or restrict it to locations within a tile (pessimistic).
