This will link functions combining multiple shaders from the same stage
into a single shader. Unlike alot of the glsl ir linker that has been
converted to NIR the logic here is completely different from the glsl ir
code that linked functions. The existing nir cloning code allows us to
implement this functionality in a much more eligant way than what glsl
ir was doing.

This will be use by the glsl nir linker when we are combining
different shaders from the same shader stage that might have multiple
declarations of global variables across the different shaders.

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.

`shader-db` uses its output, and with its 8-10min runtime it can't be
ignored and should be counted with the other test jobs.
This makes the critical build jobs a bit slower but makes the overall
pipeline shorter when the test jobs respect the 15min deadline.

If the shader has multiple payload variables, split passes might not
preserve the order and this can cause the offsets used for the stores to
not match the payload offsets for nir_intrinsic_trace_ray.

There's never any need for anything higher. If this were too high (such
as NIR_ALIGN_MUL_MAX), it would have caused issues.

In the RT shader, if there's a executeCallableEXT() in between,
even though the called shader does nothing, the instructions before and
after the executeCallableEXT() is not properly synced.
Patch fixes:

Thank to Kevin for finding out there is a load/store issue.

In commit 44351d67f8, I needed to change some variables in a check for
compression in anv_can_fast_clear_color_view(). Instead of doing that, I
dropped the check altogether because I thought the call to
anv_layout_to_fast_clear_type() which followed right afterwards would
return ANV_FAST_CLEAR_NONE if the aux usage was ISL_AUX_USAGE_NONE.
That turned out not to be the case, due to special-casing of Xe2+. For
now, make Xe2+ more like other platforms when it comes to enabling
fast-clears. If there comes a reason to actually fast-clear with
ISL_AUX_USAGE_NONE, we can revisit this.

Instead of unconditionally emitting a warning to applications about
the missing environment variable to enable the driver, only check it
after determining that the device actually matches.
