The set of blend shaders is closed. They are completely internal. As such, we
know that the registers we reserve for them suffice, and we don't permit
register spilling. Refusing to support spilling in blend shaders simplifies a
number of parts of the compiler. Add a check that we don't try to spill anyway,
which will silently fail.

BIFROST_MESA_DEBUG=spill now restricts the register file to 1/4 its usual size,
useful for testing register spilling (e.g. running CTS) as well as debugging
spilling on small shaders.
Note blend shaders are exempt, as we don't allow blend shaders to spill.

Without --quiet glslang unconditionally prints the input file name to stdout.
Check if --quiet is supported because some distros only have ancient glslang
versions.

Fixes failures on tests like this when the on-disk-cache is enabled:
dEQP-VK.binding_model.descriptor_copy.compute.uniform_buffer_0
We only found them when running full CTS runs. What happens is that we
got a hit from the on-disk shader cache, for several tests using the
same shaders. But some tests seems to be using a uniform buffer, and
others a inline buffer. Right now inline buffers leads to some changes
on the final nir shader, and generated assembly, compared with uniform
buffers. So we got a wrong shader. Fortunately we only got an assert
instead of weird behaviour.
With this commit we include the pipeline layout on the pipeline sha1,
so those two cases would get different sha1. FWIW, this is what other
drivers are already doing.
Surprisingly that didn't cause a problem before.

If we are calling pipeline_cache_upload_shared_data with
from_disk_cache, that means that we had used the disk-cache to found
that entry. And that should only happens if we didn't find the entry
on the cache. So on that case we can skip to search for it.

The early-Z buffer may load incorrect depth values if the frame has an
od width or height. In this case we need to disable early-Z.
v3:
- Set job->early_zs_clear only for V3D_VERSION >= 40 (Iago)
- Check early-Z is disabled if no zsbuf (Iago)
v4:
- Borrow comments from v3dv around v3d_update_job_ez() (Iago)

From the GL 4.6 spec: "If the value of any non-ignored component of the
offset vector operand is outside implementation-dependent limits, the
results of the texture lookup are undefined." We shouldn't assertion
fail, then.
GLSL-to-NIR shouldn't be enforcing limits on TG4 offsets, since it doesn't
for non-TG4 tex_src_offset either. Leave it up to the driver to handle
it.
Fixes a crash in a piglit test on nouveau that supplies a negative random
number up to 10,000 as the first coordinate for some reason. Other NIR
drivers lowered TG4 explicit offsets to tex_src_offset, so they weren't
affected.

This is deterministic, unlike a set. Note we need the extra dereferencing to
keep the macro safe, simple, and standards compliant:
1. Nesting two for-loops would cause break/continue to fail.
2. Declaring variables outside the loop would pollute the namespace.
3. Declaring an anonymous struct is not conformant and doesn't compile in clang.
