spirv: Clean up vtn_pointer_to_offset

spirv: Make push constants an offset-based pointer
Push constants have been a weird edge-case for a while in that they have
explitic offsets but we've been internally building access chains for
them. This mostly works but it means that passing pointers to push
constants through as function arguments is broken. The easy thing to do
for now is to just treat them like UBOs or SSBOs only without a block
index. This does loose a bit of information since we no longer have an
accurate access range and any indirect access will look like it could
read the whole block. Unfortunately, there's not much we can do about
that. Once NIR derefs get a bit more powerful, we can plumb these
through as derefs and be able to reason about them again.

The name is just a debug hint.
Instead of checking for the name this patch makes it check for

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

spirv: Get rid of vtn_variable_mode_image/sampler
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.

nir/lower_samplers: Limit assert to GLSL shader programs
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.

mesa/main: Add a 'spirv' flag to gl_shader_program_data
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.

year period, during which the tests were not run.
v2: use raise Exception() over print() & return false (Dylan)

Bring back the "detection" of the said variables, to allow
standalone execution.
