This makes the config file easier to read, and also shaves 5-10 seconds
of deqp-run per job, but that's cancelled out by all the random network
delays of everything else in the job so we'll never actually notice the
difference.

This has been confusing for some time, as from a xml file with the
suffix v33 (so suggesting just one version) we were generating the
headers for v33, v40, v41 and v71.
So now there is a header for the vc4 driver, and one header for the
v3d/v3dv (so v3d "platform") drivers.
FWIW, this means that now the name of the original xml and the header
files generated doesn't maintain a so similar pattern, but again the
equivalence were not there anyway.

So far we were packing by hand unnormalized coordinates at the
V3D41_TMU_CONFIG_PARAMETER_1 pack structure. To get this working we
hardcoded V3D_VERSION to 41 at v3dv_uniforms, that works for v71
because the structure are the same. But that is somewhat ugly, and
will not work if a new hw generation have a different structure.
Additionally, we found that for v3d this will be also needed.
So this commit adds a helper on the compiler. For now, and to simplify
it also use just one method for both generations. This solves the
problem of the same code needed on both v3d and v3dv.
But the idea is that in the future we need a similar need, but the
structure different on each generation, it would have used a similar
approach to other generation dependent function calls (like
v3d40_vir_emit_tex), having the implementation on a source file that
can safely include the hw generation headers.

ldunifa works exactly the same as ldunif: the hw will prefetch the
next 4 bytes after a read, so if a buffer is exactly a multiple of
a page size and a shader uses ldunifa to read exactly the last 4 bytes
the prefetch will read out of bounds and spam the error on the kernel
log. Avoid that by allocating extra bytes in this scenario.

This is the original definition for ANYOPMASK, until we found that
clang raised a warning using the option shift-count-overflow, so we
used an alternative.
That warning was fixed with commit 6e2bb716b0, so let's restore
previous version.
Note that other good thing of that warning being fixed is that now we
can use without warning OP_RANGE with bit 63 (in the case that any
broadcom opcode used that bit)

We have been using drm_render_device to refer to the render device and
drm_primary_device to refer to the display device, but that is confusing
because the render device also has a primary node (for legacy reasons),
so don't use primary to refer to the display device.

In v3d 4.x we handle formats that are reversed or R/B swapped by
applying a format swizzle. This doesn't work on border colors though,
and for that there is a specific bit to reverse the border color in
the texture shader state.
In v3d 7.x we have new reverse and swap R/B bits and we no longer have
a bit to reverse the border color because the new reverse bit applies
to border texels too. Because of this, we absolutely need to use these
new bits in order to get correct border colors in all cases with these
formats.
When we enable the reverse and/or swap R/B bits, we are effectively
applying the format swizzle through them, so in these cases we need to
make sure the swizzle we program in the texture shader state is the
view swizzle provided by the API and not the composition of the format
swizzle with the view swizzle like we do in 4.x for all formats. The
same applies to custom border colors: we must not apply the format
swizzle to them for formats that are reversed or R/B swapped, because
again, this format swizzle is already applied through these new bits.
While we are doing this, we also fully adopt the texture shader state
spec from v3d 7.1.5 for v3d 7.x instead of using a description from
7.1.2 which is incompatible and required the driver to manually pack
some of the bits.

When the Z scale is too small guardband clipping may not clip
correctly, so disable it, which is a new option in V3D 7.x.
This fixes this test in V3D 7.x without needing any workarounds:
