degenerate-prims: Add tests that draw one primitive and have some extra data
For GL_LINES, GL_TRIANGLES, GL_QUADS, and GL_QUAD_STRIP, add tests that
are one vertex short of two primitives. This should draw something. We
don't check exactly what's drawn because, well, it's hard. This is
mostly try to reproduce a crash in some Mesa drivers.
