This helper was only called from _mesa_BindTextureUnit(). It's simpler
to just inline it.
The error check / code / message in the helper was incorrect. It was
written for glBindTextures(), not glBindTextureUnit(). The correct
error for a bad texture unit number is GL_INVALID_VALUE. The error
message now reports the unit number rather than a GL_TEXTUREi enum.

The old code had some significant problems with respect to
sampler2DArray textures. The biggest problem was that some of the code
would use vec3 for the texture coordinate type, and other parts of the
code would use vec2. The resulting shader would not even compile.
Since there were not tests for this path, nobody noticed.
The input to the fragment shader is always treated as a vec3. If the
source data is only vec2, the vertex puller will supply 0 for the .z
component. The texture coordinate passed to the fragment shader is
always a vec2 that comes from the .xy part of the vertex shader input.
The layer, taken from the .z of the vertex shader input is passed
separately as a flat integer. If the generated fragment shader does not
use the layer integer, the GLSL linker will eliminate all the dead code
in the vertex shader.

gl_texture_2d_multisample_array", etc. on i965.

i915 fragment programs utilize the texture coordinate registers
for both texture coordinates and varyings. Unfortunately the
code doesn't check if the same index might be in use for both.
It just naively uses the index to pick a texture unit, which
could lead to collisions.
Add an extra mapping step to allocate non conflicting texture
units for both uses.
The issue can be reproduced with a pair of simple shaders like
these:
attribute vec4 in_mod;
varying vec4 mod;
void main() {
mod = in_mod;
gl_TexCoord[0] = gl_MultiTexCoord0;
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;

Broadwell's 3DSTATE_GS contains new "Static Output" and "Static Vertex
Count" fields, which control a new optimization. Normally, geometry
shaders can output arbitrary numbers of vertices, which means that
resource allocation has to be done on the fly. However, if the number
of vertices is statically known, the hardware can pre-allocate resources
up front, which is more efficient.
Thanks to the new NIR GS intrinsics, this is easy. We just call the
function introduced in the previous commit to get the vertex count.
If it obtains a count, we stop emitting the extra 32-bit "Vertex Count"
field in the VUE, and instead fill out the 3DSTATE_GS fields.

The visitor was setting a mlen that was wrong for Broadwell, but the
generator was ignoring it and doing the right thing regardless. We may
as well move the logic fully into the visitor. This will be useful in
the next commit as well.

Some hardware (such as Broadwell) can run geometry shaders more
efficiently when the number of vertices emitted is statically known.
This pass provides a way to obtain the constant vertex count, or
-1 indicating that the vertex count is unknown/non-constant.

The old code was disasterously complex - spread across multiple atoms
which may not even run, inspecting the dirty bits to try and decide
whether it was necessary to do checks...storing VS information in
brw_context...extra flagging...
This code tripped me and Carl up very badly when working on the
shader cache code. It's very fragile and hard to maintain.
Now that geometry shaders only depend on their inputs and don't have
to worry about the VS VUE map, we can dramatically simplify this:
just compute the VUE map coming out of the geometry shader stage
in brw_upload_programs. If it changes, flag it. Done.
v2: Also check vue_map.separable.

Because we only support geometry shaders in core profile, we can safely
ignore any driver-extending of VS outputs.
Those are:
- Legacy userclipping (doesn't exist in core profile)
- Edgeflag copying (Gen4-5 only, no GS support)
- Point coord replacement (Gen4-5 only, no GS support)
- front/back color hacks (Gen4-5 only, no GS support)
v2: Rebase; leave a comment about why SSO works.

Previously, our VUE map code always assigned slots to varyings
sequentially, in one contiguous block.
This was a bad fit for separate shaders - the GS input layout depended
or the VS output layout, so if we swapped out vertex shaders, we might
have to recompile the GS on the fly - which rather defeats the point of
using separate shader objects. (Tessellation would suffer from this
as well - we could have to recompile the HS, DS, and GS.)
Instead, this patch makes the VUE map for separate shaders use a fixed
layout, based on the input/output variable's location field. (This is
either specified by layout(location = ...) or assigned by the linker.)
Corresponding inputs/outputs will match up by location; if there's a
mismatch, we're allowed to have undefined behavior.
This may be less efficient - depending what locations were chosen, we
may have empty padding slots in the VUE. But applications presumably
use small consecutive integers for locations, so it hopefully won't be
much worse in practice.
3% of Dota 2 Reborn shaders are hurt, but only by 2 instructions.
This seems like a small price to pay for avoiding recompiles.

Our plan of assigning consecutive slots doesn't work properly for
separate shader objects - at least, if we want to avoid recompiling them
whenever the interface changes.
As a first step, make assign_vue_map take an explicit slot parameter,
rather than implicitly incrementing it.

Nothing actually relies on unused slots being initialized to
BRW_VARYING_SLOT_COUNT. Soon, we're going to have VUE maps with holes
in them, at which point pre-filling with BRW_VARYING_SLOT_PAD make a lot
more sense.

We can't just break for padding slots. Instead, treat them like
unwritten output variables, so we handle flushing and incrementing
urb_offset correctly.
Paul introduced the concept of padding slots back in 2011, but we've
never actually used them for anything. So it's unsurprising that the
scalar VS backend didn't handle them quite right.
