This worked because the optimizer didn't consider that the 16-bit
instruction would interpret the inline constant differently. This will
change in the next commit.

It's tricky to merge XFB-outputs correctly, because we need there to not
be any overlaps when we get to `nir_gather_xfb_info_with_varyings` later
on. We currently trigger an assert there if we end up merging here.
So let's not even try. This is an optimization, and we can optimize this
in safe cases later if needed. For now, let's play it safe.

The only reason for this dependency was the fd_bo used for the uploaded
shader. But this isn't used by turnip. Now that we've unified the
cleanup path from gallium, it isn't hard to pull the fd_bo upload/free
parts into ir3_gallium.
This cleanup has the added benefit that the shader disk-cache will not
have to deal with it.

glsl builtins that have no analog in spirv are emitted as regular varyings,
which means they take up a slot.
we need to ensure that there's no conflict between these regular varying
slots (from user-defined varyings) and the glsl translated builtins, so
we do that by "reserving" the max number of varying slots that can be used
by a given stage, then remapping all glsl builtins with no spirv builtin
to a packed layout location that can be consistent across stages
sort of addresses mesa/mesa#3113 except now there's 10 fewer varying slots

This seems valid per the SPIR-V spec to use OpSampledImage with
OpUndef instead of OpTypeImage or OpTypeSampler. When the image
operand is undefined, SPIRV->NIR emits an undef instruction that
can be removed later by the compiler.

Instead of requiring an explicit unoptimized move, we can implicitly
colour the blend input intrinsic to r0, where it will be preloaded; this
is a simple task for RA, and does not conflict with anything. If there
are multiple duplicate loads, the latter ones can just be simple moves
which will be copypropped.
We don't need to include a explicit synthetic load, since (scanning
backwards) the read will cause the input to become live at the right
time and the lack of an explicit write will keep it live from the
beginning of the shader. So no need to make it more complicated than it
needs to be.
Saves a cycle in blend shaders.

Old script created files in the source directory, which is generally
considered bad form.
The rewrite to python instead of duct-taping around in the shell script
goes towards the goal of only having cross-platform python scripts,
which is also harder to make mistakes in than shell scripts.

I'm not 100% sure if it feels right to update these. I mean, this keeps
links working as they should, even if exported to something else than
HTML. But it also feels a bit like history revisionism. It's probably
the right thing to do, though.

This kind of only makes sense once we have a separate home-page. But I
think this is a good way of showing why we should do this; Sphinx
doesn't support pagination, because it's not meant as a general-purpose
website framewrork. And for documentation, pagination is not really
something you need.
There's probably a lot more pages that should be moved into a separate
webpage, similar to this. In general, I think this should be done for
pages that don't relate to the source code too much, e.g isn't needed to
understand the code, or for instance explains how to get the source code.
