the pushbuffer is flushed, which through flush_notify ->
nv50_default_flush_notify -> nouveau_fence_update marks currently
emitting fence as flushed. But actual emission is done after this mark.
So later when there is a need to wait on this fence and pushbuffer
was not flushed in between, fence wait will never finish causing
application to hang.
To fix this, introduce new fence state between AVAILABLE and EMITTED,
set it before emission and handle it everywhere.

Previously, if the user enabled a non-consecutive set of clip planes
(e.g. 0, 1, and 3), the driver would compact them down to a
consecutive set starting at 0. This optimization was of dubious
value, and complicated the implementation of gl_ClipDistance.
This patch changes the driver so that with Gen6 and later chipsets, we
no longer compact the clip planes. However, we still discard any clip
planes beyond the highest number that is in use, so performance should
not be affected for applications that use clip planes consecutively
from 0.
With chipsets previous to Gen6, we still compact the clip planes,

The patch adds a field to the vertex shader cache key,
userclip_planes_enabled, to store the current value of
ctx->Transform.ClipPlanesEnabled. Also, it changes
setup_uniform_clipplane_values() to read from this new field, so that
it's manifestly clear that the vertex shader isn't depending on state

Note: when the vertex shader uses gl_ClipDistance, the VS backend
doesn't need to know which clip planes are in use, so we leave the
field as zero in that case to avoid unnecessary recompiles.

i965: Rearrange VS cache key struct.
No functional change. This patch rearranges the struct
brw_vs_prog_key so that the two fields related to clipping are
together, and documents those fields. This should make the patches
that follow easier to comprehend, since they add additional
clipping-related fields to this structure.

mesa: Create _mesa_bitcount_64() to replace i965's brw_count_bits()
The i965 driver already had a function to count bits in a 64-bit uint
(brw_count_bits()), but it was buggy (it only counted the bottom 32
bits) and it was clumsy (it had a strange and broken fallback for
non-GCC-like compilers, which fortunately was never used). Since Mesa
already has a _mesa_bitcount() function, it seems better to just
create a _mesa_bitcount_64() function rather than special-case this in
the i965 driver.
This patch creates the new _mesa_bitcount_64() function and rewrites
all of the old brw_count_bits() calls to refer to it.

i965 Gen6: Implement gl_ClipVertex.
This patch implements proper support for gl_ClipVertex by causing the
new VS backend to populate the clip distance VUE slots using
VERT_RESULT_CLIP_VERTEX when appropriate, and by using the
untransformed clip planes in ctx->Transform.EyeUserPlane rather than
the transformed clip planes in ctx->Transform._ClipUserPlane when a
GLSL-based vertex shader is in use.
When not using a GLSL-based vertex shader, we use
ctx->Transform._ClipUserPlane (which is what we used prior to this
patch). This ensures that clipping is still performed correctly for
fixed function and ARB vertex programs. A new function,
brw_select_clip_planes() is used to determine whether to use
_ClipUserPlane or EyeUserPlane, so that the logic for making this
decision is shared between the new and old vertex shaders.
Fixes the following Piglit tests on i965 Gen6:
- vs-clip-vertex-const-accept
- vs-clip-vertex-const-reject
- vs-clip-vertex-different-from-position
- vs-clip-vertex-equal-to-position
- vs-clip-vertex-homogeneity
- vs-clip-based-on-position
- vs-clip-based-on-position-homogeneity
- clip-plane-transformation clipvert_pos
- clip-plane-transformation pos_clipvert

mesa: Add a gl_vert_result for gl_ClipVertex.
Before this patch, clip planes didn't work properly in Mesa when using
vertex shaders, because Mesa assigned both gl_ClipVertex and
gl_Position to the same gl_vert_result (VERT_RESULT_HPOS). As a
result, backends couldn't distinguish between the two variables, so
any shader that wrote different values to them would fail to work
properly.
This patch paves the way for proper support of gl_ClipVertex by
creating a new enumerated value in gl_vert_result for it
(VERT_RESULT_CLIP_VERTEX). After this patch, a back-end may add
support for gl_ClipVertex using the following algorithm:
- If using a user-supplied GLSL vertex shader:
- If the bit corresponding to VERT_RESULT_CLIP_VERTEX is set in
gl_program::OutputsWritten:
- Clip using the vertex shader output VERT_RESULT_CLIP_VERTEX and
the clip planes defined in gl_context::Transform.EyeUserPlane.
- Else:
- Clip using the vertex shader output VERT_RESULT_HPOS and the
clip planes defined in gl_context::Transform.EyeUserPlane.
- Else (either using fixed function or an ARB vertex program):
- Clip using the vertex shader output VERT_RESULT_HPOS and the clip
planes defined in gl_context::Transform._ClipUserPlane (*)
where (*) represents the normal Mesa behavior before this patch.
An example of implementing the above algorithm can be found in the
patch that follows this one, which implements gl_ClipVertex in i965
Gen6.

llvmpipe has a few special rasterization paths for triangles contained in
16x16 blocks, but it allows the 16x16 block to be aligned only to a 4x4

Some 16x16 blocks could actually intersect the tile
if the triangle is 16 pixels in one dimension but 4 in the other, causing
a buffer overflow.
The fix consists of budging the 16x16 blocks back inside the tile.
