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

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

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) {

      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
