mesa: check for z=0 in _mesa_Vertex3dv()
It's very rare that a GL app calls glVertex3dv(), but one in particular
calls it lot, always with Z = 0. Check for that condition and convert
the call into glVertex2f. This reduces VBO memory used and reduces
the number of times we have to switch between float[2] and float[3]
vertex formats in the svga driver. This results in a small but
measurable performance improvement.
