i965: Don't check for format differences when using the blorp blitter
Previously the blorp blitter wouldn't be used if the source and destination
buffer had a different format other than swizzling between RGB and BGR and
adding or removing a dummy alpha channel. However there's no reason why the
blorp code path can't be used to do almost all format conversions so this
patch just removes the checks. However it does explicitly disable converting
to/from MESA_FORMAT_Z24_UNORM_X8_UINT because there is a similar check
brw_blorp_copytexsubimage.
This doesn't cause any Piglit test regressions at least on Ivybridge.

Different generations of hardware measure jump distances in different

coded this scaling, or made a hardcoded assumption (i.e. just used 2).
Most functions start with the number of instructions to jump, and scale
up to the hardware-specific value. So, I made the function match that.
Others start with a byte offset, and divide by a constant (8) to obtain
the jump distance. This is actually 16 / 2 (the jump scale for Gen5-7).

i965/clip: Removing scissor atom
Now that we no longer use ctx->DrawBuffer->_Xmin and related fields to
program the screen-space viewport extents, we don't depend on any
scissoring state. So we can drop the +_NEW_SCISSOR dependency.
On GEN8, a change in scissor state does not effect anything for the
clipper/sf hardware state. The hardware will always do the right thing
once the viewport extents are programmed. We can therefore remove the
unecessary state emission.

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).

draw: hack around weird primitive id input in gs
The distinction between system values and ordinary inputs is not very
obvious in gallium - further fueled by the fact that they use the same
semantic names.
Still, if there's any value which imho really is a system value, it's the
primitive id input into the gs (while earlier (tessleation) stages could read
it, it is _always_ generated by the system). For some odd reason though (which
I'd classify as a bug but seems too complicated to fix) the glsl compiler in
mesa treats this as an ordinary varying, and everything else after that
(including the state tracker and other drivers) just go along with that.
But input fetching in gs for llvm based draw was definitely limited to the
ordinary (2-dimensional) inputs so only worked with other state trackers,
the code was also additionally relying on tgsi_scan_shader filling
uses_primid correctly which did not happen neither (would set it only for
all stages if it was a system value, but only set it for the fragment shader
if it was an input value).
This fixes piglit glsl-1.50-geometry-primitive-id-restart and primitive-id-in
in llvmpipe.

Previously, we explicitly set the execution size to BRW_EXECUTE_8 and
disabled compression for loop instructions. I can't imagine how this
could be correct in SIMD16 mode.
Looking at the history, it appears that this code has used BRW_EXECUTE_8
since 2007, when we had a SIMD8 backend that supported control flow and
a separate SIMD16 backend that didn't. Presumably, when we added SIMD16
support for shaders with control flow, we simply neglected to update it.
Note that Gen4-5 don't support SIMD16 on shaders with control flow.
This might be a candidate for stable, but would need to be rewritten
completely due to the brw_inst API changes in master.
