gl_VertexID sequence is not correct in non-index drawing
OpenGL ES 3.0 Mesa 11.2.0 in HSW generates incorrect gl_VertexID sequence.
e.g. when I draw as follows
glDrawArrays(GL_POINTS, 0, 1000);
max gl_VertexID is not 999, but about 1200, while total vertext number is 1000.
It means gl_VertexID skips some number.
In the attachment, red points are inside max gl_VertexID, while green points
are outside max gl_VertexID. You can see lots of skipped gl_VertexID also.</pre>
