This makes it possible to skip urb re-configuration if the
subsequent renders agree with the settings.
Also allows blorp to allocate the maximun amount of vs entries
available. Core upload logic already knows how to calculate this.

Packet 3DSTATE_CONSTANT_PS is still emitted explicitly as ps stage
itself is enabled and hardware may try to prefetch constants from
the buffer. From the BSpec: 3D Pipeline - Windower -
3DSTATE_PUSH_CONSTANT_ALLOC_PS
"Specifies the size of the PS constant buffer. This value will
determine the amount of data the command stream can pre-fetch
before the buffer is full."
This is not possible on gen6. From the BSpec about 3DSTATE_CONSTANT_PS:
"This packet must be followed by WM_STATE."
Binding table emissions for stages other than PS can be now dropped,
they were only needed for the 3DSTATE_CONSTANT_XS to be effective:
From the BSpec:
"The 3DSTATE_CONSTANT_* command is not committed to the shader unit
until the corresponding (same shader) 3DSTATE_BINDING_TABLE_POINTER_*
command is parsed."

Some games are sloppy.. perhaps because it is defined behavior for DX or

Fixes:
GL44-CTS.texture_barrier_ARB.same-texel-rw-multipass
On Haswell, Broadwell and Skylake (note that in order to execute that
test, it is needed to override GL and GLSL versions).
On gen6 this test was already working without this change. It keeps
working after it.
This commit replaces the call to brw_emit_mi_flush for gen6+ with two
calls to brw_emit_pipe_control_flush:
* The first one with RENDER_TARGET_FLUSH and CS_STALL set to initiate
a render cache flush after any concurrent rendering completes and
cause the CS to stop parsing commands until the render cache
becomes coherent with memory.
* The second one have TEXTURE_CACHE_INVALIDATE set (and no CS stall)
to clean up any stale data from the sampler caches before rendering
continues.
Didn't touch gen4-5, basically because I don't have a way to test
them.

Thanks to Curro to help to tracking this down, as the root case was a
hw race condition.
v2: use two calls to pipe_control_flush instead of a combination of
gen7_emit_cs_stall_flush and brw_emit_mi_flush calls (Curro)

This reverts commit 644e015f0b9236e955d679cac4bcc7a1523fc475.
PrimitiveMode from the program doesn't always hold a valid value that
is neither of GL_TRIANGLES, GL_QUADS nor GL_ISOLINES when reaching
this code. This caused regressions in the following CTS tests:
GL44-CTS.stencil_texturing.functional
GL44-CTS.shading_language_420pack.binding_images
GL44-CTS.shading_language_420pack.binding_samplers
GL44-CTS.shading_language_420pack.binding_uniform_single_block

GL44-CTS.shading_language_420pack.length_of_vector_and_matrix

Hence, we rather take it from the linked shader.

There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.
The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.
We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

emit_urb_writes() contains code to emit an EOT write with no actual
data when there are no output varyings. This makes sense for the VS
and TES stages, where it's called once at the end of the program.
However, in the geometry shader stage, emit_urb_writes() is called once
for every EmitVertex(). We explicitly emit a URB write with EOT set at
the end of the shader, separately from this path. So we'd better not
terminate the thread. This could get us into trouble for shaders which
do EmitVertex() with no varyings followed by SSBO/image/atomic writes.
It also caused us to emit multiple sends with EOT set, which apparently
confuses the register allocator into not using g112-g127 for all but
the first one. This caused EU validation failures in OglGSCloth
shaders in shader-db. (The actual application was fine, but shader-db
thinks there are no outputs because it doesn't understand transform
feedback.)

On MRF platforms, we need to set base_mrf to the first MRF value we'd
like to use for the message. On send-from-GRF platforms, we set it to
-1 to indicate that the operation doesn't use MRFs.
As MRF platforms are becoming increasingly a thing of the past, we've
forgotten to bother with this. It makes more sense to set it to -1 by
default, so we don't have to think about it for new code.
I searched the code for every instance of 'mlen =' in brw_fs*cpp, and
it appears that all MRF-based messages correctly program a base_mrf.
Forgetting to set base_mrf = -1 can confuse the register allocator,
causing it to think we have a large fake-MRF region. This ends up
moving the send-with-EOT registers earlier, sometimes even out of
the g112-g127 range, which is illegal. For example, this fixes
illegal sends in Piglit's arb_gpu_shader_fp64-layout-std430-fp64-shader,
which had SSBO messages with mlen > 0 but base_mrf == 0.

The old return type of GLuint was wonky - it should have been bool.
But nothing actually uses the return value anyway, so we can just drop
that and make it a void function.
In theory, it might make sense to ask whether the texture validated
successfully, but just checking intel_obj->mt != NULL works for that.

We currently use CL_INVOCATION_COUNT for the GL_PRIMITIVES_GENERATED
query, which involves passing all primitives to the clipper. When
rasterizer discard is enabled, we program the clipper in REJECT_ALL
mode, rather than using the SOL stage's "Rendering Disable" feature.
See commit f09b91f78247409f54c975f56cb10d5f350fe64e for an explanation
of why we implement GL_PRIMITIVES_GENERATED this way.
Apparently the SOL stage's "Rendering Disable" feature is a lot faster
than having the clipper reject all primitives. It's safe to use when
no GL_PRIMITIVES_GENERATED query is active, as we don't care about
CL_INVOCATION_COUNT incrementing.
This patch makes us use SO_RENDERING_DISABLE when no query is active,
but continues falling back to the clipper in REJECT_ALL mode when the
queries are enabled. It brings back the perf_debug for the clipper
case (which I removed in commit 1f9445ff57b, thinking it wasn't useful).
