Fixes various test fallout from 90b5a2425a on Pineview, which claims to
support ARB_internalformat_query but doesn't actually provide the
driverfunc.
That driver is still broken [GetInternalformativ will still segfault!]
but it was silly to be going through the sample count logic in the
nonmultisampling case at all.

With the introduction of geometry shaders, fragment inputs will no
longer come exclusively from the vertex shader; sometimes they come
from the geometry shader. So the name "vp_outputs_written" will
become a misnomer. This patch renames vp_outputs_written to
input_slots_valid, to reflect the true meaning of the bitfield from
the fragment shader's point of view: it indicates which of the
possible input slots contain valid data that was written by the
previous shader stage.

This patch modifies post-GS pipeline stages (transform feedback, clip,
sf, fs) to refer to the VUE map through brw->vue_map_geom_out rather
than brw->vs.prog_data->vue_map. This ensures that when geometry
shader support is added, these pipeline stages will consult the
geometry shader output VUE map when appropriate, rather than the
vertex shader output VUE map.
v2: Fixed some stale "CACHE_NEW_VS_PROG" comments.
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
Currently, the GPU pipeline has one active VUE map in effect at any
given time--the one representing the layout of vertex data coming from
the vertex shader. However, when geometry shaders are added, they
will have their own independent VUE map. Later pipeline stages (clip,
sf, fs) will need to consult the geometry shader VUE map if a geometry
shader is in use, and the vertex shader VUE map otherwise.
This patch adds a new field to brw_context, vue_map_geom_out, which
contains the VUE map that should be used by later pipeline stages. It
also adds a new state flag, BRW_NEW_VUE_MAP_GEOM_OUT, which is
signalled whenever the contents of the VUE map changes.
Since we don't support geometry shaders yet, vue_map_geom_out is
currently set only by the brw_vs_prog state atom.
v2: Don't set vue_map_geom_out in do_vs_prog--that's redundant and
possibly problematic for precompiles. Only set it in
brw_upload_vs_prog. Also, make a copy instead of using a
pointer--this makes it possible to detect when the VUE map hasn't
changed, so we can avoid redundant state uploads.

Future patches will allow for there to be separate VUE maps when both
a geometry shader and a vertex shader are in use. When this happens,
we will want to have correspondingly separate outputs_written
bitfields. Moving outputs_written into the VUE map will make this
easy.
For consistency with the terminology used in the VUE map, the bitfield
is renamed to "slots_valid" in the process.

Gen7 adds mask bits to the message header for a URB write which allow
the write to apply only to certain channels. We don't use this
functionality, so to ensure that the entire write always occurs, we
emit an OR instruction to set the mask bits.
With the advent of geometry shaders, URB writes won't just happen at
the end of a thread; they will happen in mid-thread too. Thus, we can
no longer rely on channel 0 being enabled, so we need to emit the OR
instruction in WE_all mode to ensure that it is executed.

The new name clarifies that it represents *one more* than the maximum
possible brw_varying_slot value.
Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>
This patch removes the terminology "vert_result" from the i965 driver,
replacing it with "varying". The old terminology, "vert_result", was
confusing because (a) it referred to the enum gl_vert_result, which no
longer exists (it was replaced with gl_varying_slot), and (b) it
implied a vertex output, but with the advent of geometry shaders, it
could be either a vertex or a geometry output, depending what shaders
are in use. The generic term "varying" is less confusing.
No functional change.
