Piglit was recently changed to expect the correct error code (piglit
commit 271b998), so it started failing on Mesa. This corrects that
failing and adds some spec quotations to justify the errrors set.
The code was rearranged a little bit to match the order listed in the
spec.

brw_queryobj.c needs a version of write_timestamp that works on all
generations for the QueryCounter() driver hook. So there's no point in
duplicating it in gen6_queryobj.c.

Previously, Mesa enforced the following rule (from
ARB_geometry_shader4's list of criteria for framebuffer completeness):
* If any framebuffer attachment is layered, all attachments must have
the same layer count. For three-dimensional textures, the layer count
is the depth of the attached volume. For cube map textures, the layer
count is always six. For one- and two-dimensional array textures, the
layer count is simply the number of layers in the array texture.
{ FRAMEBUFFER_INCOMPLETE_LAYER_COUNT_ARB }
However, when ARB_geometry_shader4 was adopted into GL 3.2, this rule
was dropped; GL 3.2 permits different attachments to have different
layer counts. This patch brings Mesa in line with GL 3.2.
In order to ensure that layered clears properly clear all layers, we
now have to keep track of the maximum number of layers in a layered
framebuffer.
Fixes the following piglit tests in spec/!OpenGL 3.2/layered-rendering:
- clear-color-all-types 1d_array mipmapped
- clear-color-all-types 1d_array single_level
- clear-color-mismatched-layer-count
- framebuffer-layer-count-mismatch

From section 4.4.4 (Framebuffer Completeness) of the GL 3.2 spec:
If any framebuffer attachment is layered, all populated
attachments must be layered. Additionally, all populated color
attachments must be from textures of the same target.
We weren't checking that the attachments were from textures of the
same target.

Commit 1a92881 added extra flushes to fix a HiZ hang in
WebGL Google Maps. With the extra flushes emitted by the previous two
patches, the flushes added by 1a92881 are redundant.
Tested with the same criteria as in 1a92881: by zooming in and out
continuously for 2 hours on Sandybridge Chrome OS (codename
Stumpy) without a hang.

Unconditionally set brw->need_workaround_flush at the top of gen6 blorp
state emission.
The art of emitting workaround flushes on Sandybridge is mysterious and
not fully understood. Ken and I believe that
intel_emit_post_sync_nonzero_flush() may be required when switching from
regular drawing to blorp. This is an extra safety measure to prevent
undiscovered difficult-to-diagnose gpu hangs.
I verified that on ChromeOS, pre-patch, need_workaround_flush was not
set at the top of blorp, as Paul expected. To verify, I inserted the
following debug code at the top of gen6_blorp_exec(), restarted the ui,
and inspected the logs in /var/log/ui. The abort gets triggered so early
that the browser never appears on the display.
static void
gen6_blorp_exec(...)
{
if (!brw->need_workaround_flush) {
fprintf(stderr, "chadv: %s:%d\n", __FILE__, __LINE__);
abort();
}
...

This patch makes the workaround code in gen6 blorp follow the pattern
established in the regular draw path. It shouldn't result in any
behavioral change.
On gen6, there are two places where we emit 3D_CMD_PRIM: brw_emit_prim()
and gen6_blorp_emit_primitive(). brw_emit_prim() sets
need_workaround_flush immediately after emitting the primitive, but
blorp does not. Blorp sets need_workaround_flush at the bottom of
brw_blorp_exec().
This patch moves the need_workaround_flush from brw_blorp_exec() to
gen6_blorp_emit_primitive(). There is no need to set
need_workaround_flush in gen7_blorp_emit_primitive() because the
workaround applies only to gen6.

We weren't handling the LUMINANCE_SNORM, LUMINANCE_ALPHA_SNORM and
INTENSITY_SNORM cases. Note that adding these cases here does not
require a driver to support rendering to these surface types. If
the driver can't do it we'll report an incomplete framebuffer.
NVIDIA doesn't support GL_EXT_texture_snorm but their driver
accepts these formats in glRenderBufferStorage().

Commit eda21d2a3010d9fc5a68b55a843c5e44b2abf8dd fixed the rasterization
of points for Direct3D but ended up breaking the rasterization of OpenGL
non-sprite points, in particular conform's pntrast.c test.
The only way to get both working is to properly honour
pipe_rasterizer::point_quad_rasterization, and follow the weird OpenGL
rule when it is false.

We definitely want to fall through to the unsynchronized map case, instead
of wasting bandwidth on a copy. Prevents a -43.2407% +/- 1.06113% (n=49)
performance regression on aa10perf when teaching glamor to provide the
GL_INVALIDATE_RANGE_BIT information.
This is a performance fix, which I usually wouldn't cherry-pick to stable.
But this was really was just a bug in the code, its presence would
discourage developers from giving us the best information they can, and I
think we've got fairly high confidence in the unsynchronized map path
already.

While incorrect, it probably wouldn't affect anyone ever: You'd have to do
an appropriately-formatted readpixels into a PBO, then overwrite the tail
end of the updated area of the PBO with glBufferSubData(), and you
wouldn't get appropriate synchronization.

The earlier assert made sure that our math didn't exceed our bounds, but
this makes sure that we don't overflow from the high bits X into the low
bits of Y. We've already put checks in intel_miptree_blit(), but I've
wanted to expand the type in our protoype from short to uint32_t, and we
could get in trouble with intel_emit_linear_blit() if we did.

Add for now some simple/basic query support (ie. things not actually
requiring the GPU). Might change around a bit when I actually add
GPU queries, but for now this enables some useful performance info
in the GALLIUM_HUD. For example:
GALLIUM_HUD=fps+batches+batches-sysmem+batches-gmem+restores,draw-calls
The driver specific specific queries are:
+ draw-calls
+ batches - number of batches per second, sum of batches-sysmem
plus batches-gmem
+ batches-gmem - render a set of tiles in GMEM, for each tile
(optionally) system mem -> gmem (restore), plus N draws,
plus gmem -> system mem (resolve) per second
+ batches-sysmem - N draws to system memory (GMEM bypass) per
second
+ restores - number of GMEM batches that required restore per
second
Ideally for GMEM rendering, you want batches-gmem to equal fps. If
the app is doing something that triggers multiple passes (ie. requires
extra round trip gmem <-> system memory) then the # of batches per
second will go up relative to fps.

The binning pass sorts vertices into which bins/tiles they apply to.
The visibility information generated during the binning pass can be
used to speed up the rendering pass by filtering out vertices which
do not apply to the current tile. See:
https://github.com/freedreno/freedreno/wiki/Adreno-tiling#optimized-approach
This brings a significant fps boost. A rough assortment of tests
(supertuxkart, etracer, tremulous, glmark2 'build' test, etc) seems
to yield a ~35-45% fps improvement.
For now, to be conservative, the binning pass is not enabled yet by
default. To enable it use:
FD_MESA_DEBUG=binning
So far I haven't found anything that breaks with binning enabled,
but I'd like a bit more testing before I enable it as default.

The hardware is broken with nonzero texel offsets and unnormalized
coordinates; instead of doing correct offsetting, we get garbage.
This just extends the existing workaround for ir_txf and
ir_tg4+gsampler2DRect to also consider ir_tex+gsampler2DRect.
Fixes broken rendering in 'tesseract' when 'mesa_texrectoffset_bug' is
not enabled; also fixes the new piglit test
'tests/spec/glsl-1.30/execution/fs-textureOffset-Rect'.
Has been broken ~forever; suggesting including this in only 10.0 because
the lowering pass doesn't exist in 9.2 or earlier so would require quite
a different patch.

This reduces confusion since gl_shader::Type is sometimes
GL_SHADER_PROGRAM_MESA but is more frequently
GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that
when switching on gl_shader::Stage, the compiler will alert if one of
the possible enum types is unhandled. Finally, many functions in
src/glsl (especially those dealing with linking) already use
gl_shader_stage to represent pipeline stages; using gl_shader::Stage
in those functions avoids the need for a conversion.
Note: in the process I changed _mesa_write_shader_to_file() so that if
it encounters an unexpected shader stage, it will use a file suffix of
"????" rather than "geom".

Previously, we had an enum called gl_shader_type which represented
pipeline stages in the order they occur in the pipeline
(i.e. MESA_SHADER_VERTEX=0, MESA_SHADER_GEOMETRY=1, etc), and several
inconsistently named functions for converting between it and other
representations:
- _mesa_shader_type_to_string: gl_shader_type -> string
- _mesa_shader_type_to_index: GLenum (GL_*_SHADER) -> gl_shader_type
- _mesa_program_target_to_index: GLenum (GL_*_PROGRAM) -> gl_shader_type
- _mesa_shader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
This patch tries to clean things up so that we use more consistent
terminology: the enum is now called gl_shader_stage (to emphasize that
it is in the order of pipeline stages), and the conversion functions are:
- _mesa_shader_stage_to_string: gl_shader_stage -> string
- _mesa_shader_enum_to_shader_stage: GLenum (GL_*_SHADER) -> gl_shader_stage
- _mesa_program_enum_to_shader_stage: GLenum (GL_*_PROGRAM) -> gl_shader_stage
- _mesa_progshader_enum_to_string: GLenum (GL_*_{SHADER,PROGRAM}) -> string
In addition, MESA_SHADER_TYPES has been renamed to MESA_SHADER_STAGES,
for consistency with the new name for the enum.
