vbo: Merge GL_QUADS drawing requests in display lists.

minecraft apparently has its piles of display lists each contain 6
instances of glBegin(GL_QUADS)/verts/glEnd(), which appear in the
compiled list as 6 prims of 4 verts each in one draw call.  We can
reduce driver overhead even more by making that one prim of 24 verts.

Improves minecraft performance by 1.6% +/- .25% (n=446)
