i965/guardband: Enable for all viewport dimensions (GEN8+)
The goal of guardband clipping is to try to avoid 3d clipping because it
is an expensive operation. When guardband clipping is disabled, all
geometry that intersects the viewport is sent to the FF 3d clipper.
Objects which are entirely enclosed within the viewport are said to be
"trivially accepted" while those entirely outside of the viewport are,
"trivially rejected".
When guardband clipping is turned on the above behavior is changed such
that if the geometry is within the guardband, and intersects the
viewport, it skips the 3d clipper. Prior to GEN8, this was problematic
if the viewport was smaller than the screen as it could allow for
rendering to occur outside of the viewport. That could be mitigated if
the programmer specified a scissor region which was less than or equal
to the viewport - but this is not required for correctness in OpenGL. In
theory you could be clever with the guardband so as not to invoke this
problem. We do not do this, and have no data that suggests we should
bother (nor the converse data).
With viewport extents in place on GEN8, it should be safe to turn on
guardband clipping for all cases
While here, add a comment to the code which confused me thoroughly.

i965: Simplify viewport extents programming on GEN8
Viewport extents are a 3rd rectangle that defines which pixels get
discarded as part of the rasterization process. The actual pixels drawn
to the screen are an intersection of the drawing rectangle, the viewport
extents, and the scissor rectangle. It permits the use of guardband
clipping in all cases (see later patch). The actual pixels drawn to the
screen are an intersection of the drawing rectangle, the viewport
extents, and the scissor rectangle.
Scissor rectangle is not super important for this discussion as it should
always help do the right thing provided the programmer uses it.
switch (viewport dimensions, drawrect dimension) {
case viewport > drawing rectangle: no effects; break;
case viewport == drawing rectangle: no effects; break;
case viewport < drawing rectangle:
Pixels (after the viewport transformation but before expensive
rastersizing and shading operations) which are outside of the
viewport are discarded.
}
I am unable to find a test case where this improves performance, but in
all my testing it doesn't hurt performance, and intuitively, it should
not ever hurt performance. It also permits us to use the guardband more
freely (see upcoming patch).

While working in this part of the code I had a great deal of trouble
understanding what it was trying to do, and matching it with the spec.
(mostly due bad wording in the PRM). To help future people, I've cleaned
up the wording and provided some ascii art.

u_primconvert: Copy min/max_index from the original primitive.
These values are supposed to be the minimum/maximum index values used to
read from the vertex buffers. This code either copies index values out of
the old IB (so, same min/max as the original draw call), or generates a
new IB (using index values between the start and the start + count of the
old array draw info, which just happens to be what min/max_index are set
to by st_draw.c).
We were incorrectly setting the max_index in the
converting-from-glDrawArrays case to the start vertex plus the number of
vertices generated in the new IB, which broke QUADS primitive conversion
on VC4 (where max_index really has to be correct, or the kernel might
reject your draw call due to buffer overflow).
