If the hardware does not support INSTANCE_INDEX natively, it will be
lowered to load_instance_id + base_instance. Otherwise, INSTANCE_ID
will be lowered to load_instance_index - base_instance.

NIR doesn't really support global instructions such as global val
initilisation. So here we add functionality to glsl_to_nir() to
put these instructions into a temporary function that will be
later inlined into main.
We give the function a name starting with gl_mesa_tmp_ as functions
starting with gl_ are reserved and will not have any clashes with
user functions, we finish the name with the blake3 of the shader
source to avoid conflicts with multiple shaders attached to a single
stage.

AGX has limited border colour hardware. To support full
customBorderColorWithoutFormat semantics, we're forced to emulate in shaders at
a substantial performance penalty. Actually, that's needed just to pass CTS
because of other hardware issues stacking on top of each others... Hooray!
Add the texops we need to facilitate efficient custom border colour lowering.

First, we need to give the parent_instr field a unique name to be able to
replace with a helper. We have parent_instr fields for both nir_src and
nir_def, so let's rename nir_src::parent_instr in preparation for rework.
This was done with a combination of sed and manual fix-ups.
Then we use semantic patches plus manual fixups:

GLSL doesn't use that type. SPIR-V used for a while but later started
relying on its own data structures and stopped using it.
See ca62e849d3 ("nir/spirv: Stop using glsl_type for function types")
If we were ever to add this one again, would be better to have a way to
grab a key for lookup that did not require allocations, right now that's
needed to inject return type as the first element in params array.
