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.
