unambiguous type information which can be safely ignored by the driver.

This fixes a crash with the recent Vulkan backend of Path Of Exile
(it uses the extension without checking if it's supported).

f1acf492de glsl: fix slow linking of uniforms in the nir linker
Currently the nir linker resizes the amount of storage needed to hold
uniform information on the fly while linking. As shaders can contain
thousands of uniforms this can be very slow. For example some Godot
shaders can take 30 seconds to compile on some machines.

In this change we count the amount of storage needed before we start
processing the uniforms. This is what the GLSL IR linker does also.

Fixes: 95f555a93a ("st/glsl_to_nir: make use of nir linker for linking uniforms")
Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/2996

f6214750eb glsl: stop cascading errors if process_parameters() fails
Generally we do not completely stop compilation as soon as we see an error,
instead we continue on to attemp to find any futher errors.

This means we shouldn't be checking state->error to see if any error has
happened during the compilation process, doing so was causing
process_parameters() to fail on completely valid functions if there was
any error found in the shader previously. This then caused the valid
functions not to be found because the paramlist was considered empty,
resulting in the compiler spewing out misleading error messages.

Here we simply add the IR error value to the param list when we have
an issue with processing a parameter, this leads to much better error
messaging.

Fixes: 53e4159eaa ("glsl: stop processing function parameters if error happened")

5580322486 tests: Make tests aware of meson test wrapper
Meson 0.55.0 will set the MESON_EXE_WRAPPER environment variable to the
joined version of that wrapper if it is needed. Our tests that take
compiled targets as arguments can use that information to run cross
built binaries, or if there isn't a wrapper and we get an ENOEXEC, we
can skip the tests gracefully.

We try to use mesonlib.split_args, which handles windows arguments
better than python's builtin shlex module, but fall back to that if the
meson module isn't available for some reason.

This takes the same callback as nir_foreach_src except it walks all phi
sources which leave a given block.

2c8c5cc87d nir/clone: Re-use clone_alu for nir_alu_instr_clone
All it takes are a couple small tweaks to the clone infrastructure to
allow us to use it without any remap table at all.  This reduces code
duplication and the chances for bugs that come with it.  In particular,
the hand-rolled nir_alu_instr_clone didn't preserve no_[un]signed_wrap,
or source/destination modifiers.

8c87082c94 nir: Validate jump instructions as an instruction type
This has the downside of putting block successor validation in two
places that are a bit further apart.  However, handling them as a
special case makes the code more confusing than needed.  At least two
different people have not noticed that we don't have jump instruction
validation in the last week or two and added it.  Being able to search
for validate_jump_instr is useful.
