softpipe always clipped using the position vector, however for unclipped
vertices it stored the position in window coordinates, however when position
and clipping are separated, we need to store the clip-space position and
the clip-space vertex clip, so we can interpolate both separately.
This means we have to take the clip space position and store it to use later.
This allows softpipe to pass all the clip-vertex piglit tests.
v2: fix llvm draw regression, the structure being passed into llvm needed
updating, remove some hardcoded ints that should have been enums while there.

This required changing the system value semantics, so we stored
a system value per vertex, instance id is the only other system
value we currently support, so I span it across the channels.
This passes the 3 vertexid-* piglit tests + lots of instanceid tests.

If draw isn't using llvm we can support vertex texture and integers,
These will be fixed up later, but for now allow this check to happen
at run-time.
v2: since 3e22c7a253 we can ask draw for a non-llvm
context. Just track if ask and set the vars accordingly. This probably isn't perfect but should cover the cases we care about.
v3: use debug option, restructure to store in screen, as suggested by Jakob.

We're not quite ready to actually support it in the implementation,
but at least this allows GL 3.0 API-reliant applications to hopefully
run successfully, though they won't get multisampling.

The EXT_texture_array required only 64, but GL 3.0 required 256.
Since we're already exposing values that can get us way beyond our
ability to map the single object directly, go ahead and expose all the
way to hardware limits.
Tested with new piglit EXT_texture_array/maxlayers on gen7.

We were doing the kill of the updated channels, then adding our copy
to the list of available stuff to copy. But if the copy was updating
its own source channels, we didn't notice, breaking this code:
R0.xyzw = arg0 + arg1;
R0.xyzw = R0.wwwx;
gl_FragColor.xyzw = clamp(R0.xyzw, 0.0, 1.0);
Fixes piglit glsl-copy-propagation-self-2.

It is unwise to use a stencil region's size to determine its
renderbuffer's size, because at region creation we fudge the width and
height to accomodate interleaved rows. (See the comment for MESA_FORMAT_S8
in intel_miptree_create()). Most users of stencil_region->{width,height}
should be converted to use stencil_rb->{Width,Height}.
We have already done the replacement in several locations. This patch
continues the replacement in {brw,gen7}_emit_depthbuffer(). To make those
functions look consistent, I've also done the equivalent replacement for
the depth buffer.

Don't create clip outputs if no clip planes are enabled.
Move clip validation after program validation: we were calling
linkage validation in case the VP needed rebuilding before the
FP was validated.
The vertex program needs to be built first because when
ClipDistance is used we'll want to only enable those outputs that
are also written.
These initialization functions weren't initializing all the fields so
some had undefined values. The callers of these functions sometimes use
a structure assignment to initialize new objects from these templates
so we'd just propagate the undefined values. That made for some confusing
info when debugging, plus it could lead to bugs.

This introduces an unspecified interpolation paramter that is only allowed for

specified interpolation, but not vice-versa.

This could lead to incorrect code when fixed regs are involved.
Surprisingly, the increased freedom actually leads to lower
register usage in some cases. Still want to find a better way
to treat constraints though ...
Always set position to insert before the current instruction,
the previous behaviour led to confusion (bug in checkPredicate
for BBs with only a single conditional branch).
