some games/apps (e.g., DOOM2016) compile+link shaders in one context
and then use them in another, expecting that the compiled shaders
will be reused. vulkan has pipeline (library) objects, which are not
specific to shaders but are in theory representing the shaders being used
thus, pipeline (library) objects need to be reusable for any case where
a shader can be reused
to handle this:
* extract pipeline library cache to a refcounted object
* store these objects on the screen
* make them owned by shaders
separable programs are slightly different since they'll use their own
fastpath, thus making their library caches owned by the programs to avoid
polluting the optimized caches

From the 96c19d23c9 commit message:
Ever since 4246c2869c and 7d85dc4f35 loop unrolling can no
longer depend on inot being eliminated from the loop
terminator condition so we need to be able to handle it.
Support these conditions here too.

While making the function public, rename it to
nir_collect_src_uniforms. The old name makes it sound like it's just a
query that doesn't have side effects. That is, however, not the case.
This is step 4 in an attempt to unify a bunch of nir_inline_uniforms.c
and lvp_inline_uniforms.c code.

We lost power in a storm, and these ones didn't come back afterwards. I
suspect I need a new PSU. And maybe some surge protection for the future.
:(
I've left the CI code in place for some day when I hopefully swap out the
power supplies.

By enabling this path, we get a 56% decrease in upload time on a texture
upload microbenchmark. This was measured on an Ice Lake with an iris
driver that tries to use the compressed format fallback path.

Add a function to create and cache the compute programs that will be
used to transcode ASTC to DXT5.
Note that the error paths in st_create_context_priv may actually lead to
segfaults if hit. I've been able to work around them by 1) moving them
further down and 2) returning early from st_glFlush if st->pipe is NULL.
I don't know if that's the right solution however.

1. Drop the commented out includes. Shader caching is disabled if those
are found.
2. Replace the active includes with "%s". Later on, we'll construct the
final strings with vasprintf. One downside to doing this is that the
glsl file extensions are no longer true. These files are now
templates.

These compute shaders are from the MIT-licensed GPU compressor, Betsy.
I have included copyright headers, inlined the __sharedOnlyBarrier macro
definition from the "UavCrossPlatform_piece_all.glsl" header when
applicable, and made the following changes to support GLES:
* Conditionally disable the const keyword in the BC3 shaders
* Make the params uniform in the BC4 shader uint2
* Avoid implicit data type conversions in the BC3 shaders
* Use constructors for array initialization in the BC1 shader
* Add precision qualifiers to the BC3 shaders
* Output to an rgba16ui image for the BC1 and BC4 shaders
* Set the version of the BC3 shaders to 310 es

The size in src[2] is in byte and needs to cover any possible data
accessed in src[0] by the indirection. That way the register
allocation is aware of what cannot be spilled for the instruction to

apps/games using separate shader objects end up passing the separable
shaders to the link_shader hook individually, which is still not ideal for
zink's usage since the more optimal path is to have all the shaders and create
a RAST+FS GPL stage that can run all the inter-stage io handlers
it IS technically possible to handle this for simple VS+FS pipelines using
GPL, however, but it's kinda gross. such shaders now use descriptor buffer
to create their own pipelines/layouts/descriptors async, and then a "separable"
variant of the gfx program can be created by fast-linking these together
the "separable" gfx program can't handle shader variants, but it can do basic
pipeline caching for PSO state changes, which makes it flexible enough to sorta
kinda maybe handle the most basic cases of separate shader objects
descriptor buffer is used because having to create and manage a separate architecture
for sets/pools/templates is too nightmarish even for me
this is, at best, a partial solution, but it's the best the vulkan api can
currently do
