llvmpipe: Respect bottom_edge_rule when computing the rasterization bounding boxes.
This was inadvertently forgotten when replacing gl_rasterization_rules
with lower_left_origin and half_pixel_center (commit
2737abb44efebfa10ac84b183c20fc5818d1514e).
This makes a difference when lower_left_origin != half_pixel_center, e.g,
D3D10.
