All of ARB_gpu_shader5 is most certainly not required for GLES 3.1
(most of it is in OES_gpu_shader5 on top of GLES 3.1).
Some of what is required from ARB_gpu_shader5 is provided by
ARB_texture_gather, so check for that. The remaining subset of
ARB_gpu_shader5 doesn't have individual extensions to check for,
but I guess it is unlikely that some driver has all of these
extensions but not, say, integer bitfield manipulation.

Previously when setting up a uniform it would try to walk the uniform
storage slots and find one that matches the name of the given
variable. However, each variable already has a location which is an
index into the UniformStorage array so we can just directly jump to
the right slot. Some of the variables take up more than one slot so we
still need to calculate how many it uses.
The main reason to do this is to support ARB_gl_spirv because in that
case the uniforms don’t have names so the previous approach won’t
work.

Right now, the BRW linker code assumes nir_variable::name is always
non-NULL, but thanks to ARB_gl_spirv we will soon be linking SPIR-V
programs, and those explicitly require matching uniforms by location.
The name is just a debug hint.
Instead of checking for the name this patch makes it check for
var->num_state_slots on the assumption that everything that had an
internal name also had some state slots. This seems likely because the
two code paths that are taken when the name begins with "gl_" already
have an assert that var->state_slots is not NULL.
v2: simplified, most of it moved to glsl/nir/spirv (Neil Roberts)
v3: check for num_state_slots instead of the name. This is needed
because we do actually have nameless builtins with SPIR-V such as
PatchVerticesIn and we want them to hit the
_mesa_add_state_reference code path (Neil Roberts)

This function will be the entry point for linking the uniforms from
the nir_shader objects associated with the gl_linked_shaders of a
program.
This patch includes initial support for linking uniforms from NIR
shaders. It is tailored for the ARB_gl_spirv needs, and it is far from
complete, but it should handle most cases of uniforms, array
uniforms, structs, samplers and images.
There are some FIXMEs related to specific features that will be
implemented in following patches, like atomic counters, UBOs and
SSBOs.
Also, note that ARB_gl_spirv makes mandatory explicit location for
normal uniforms, so this code only handles uniforms with explicit
location. But there are cases, like uniform atomic counters, that
doesn't have a location from the OpenGL point of view (they have a
binding), but that Mesa assign internally a location. That will be
handled on following patches.
A nir_linker.h file is also added. More NIR-linking related API will
be added in subsequent patches and those will include stuff from Mesa,
so reusing nir.h didn't seem a good idea.

vtn_variable_mode_image and _sampler are instead replaced with
vtn_variable_mode_uniform which encompasses both of them. In the few
places where it was neccessary to distinguish between the two, the
GLSL type of the pointer is used instead.
The main reason to do this is that on OpenGL it is permitted to put
images and samplers into structs and declare a uniform with them. That
means that variables can now have a mix of uniform, sampler and image
modes so picking a single one of those modes for a variable no longer
makes sense.
This fixes OpLoad on a sampler within a struct which was previously
using the variable mode to determine whether it was a sampler or not.
The type of the variable is a struct so it was not being considered to
be uniform mode even though the member being loaded should be sampler
mode.
The previous code appeared to be using var->interface_type as a place
to store the type of the variable without the enclosing array for
images and samplers. I guess this worked because opaque types can not
appear in interfaces so the interface_type is sort of unused. This
patch removes the overloading of var->interface_type and any places
that needed the type without the array can now just deduce it from
var->type.

Vulkan has the concept of separate image and sampler objects in the
SPIR-V code whereas GL conflates them into one. nir_lower_samplers
contains an assert to verify that sampler operand is not being set on
the nir instruction. However when the code comes from spirv_to_nir the
sampler operand is always set. GL_arb_gl_spirv explicitly states that
OpTypeSampler is not supported so it retains the GL behaviour of not
being able to seperate them. Therefore the sampler will always be the
same as the texture. This GL version of the lowering code ignores
instr->sampler and sets instr->sampler_index to the same value as
instr->texture_index. Some other places in the code (such as in
nir_print) assume that once the instruction is lowered then both
instr->texture and instr->sampler will be NULL, so to keep this
behaviour we now set instr->sampler to NULL after ignoring it to fill
in instr->sampler_index.

This will be used by the linker code to differentiate between programs
made out of SPIR-V or GLSL shaders.
This was rejected in the past, assuming that it was equivalent to
check for "shProg->_LinkedShaders[stage]->spirv_data != NULL". But:
* At some points of the linking process it would be needed to check
if _LinkerShaders[stage] is present, so the full check would be:
"shProg->_LinkedShaders[stage] != NULL &&
shProg->_LinkedShaders[stage]->spirv_data != NULL"
* Sometimes you would like to do some specific to SPIR-V
independently of the stage, or for any stage. For example, "link
all the uniforms, for all stages". In that case checking for the
flag would be equivalent to iterate all the _LinkedShaders and
check if there is any spirv_data available.
The former makes readibility really worse. Both could be solved by
adding two helpers. But adding a flag seems really more simple and
readable.
