We'll want to have only hashes in vk_pipeline_stage so the
vk_pipeline_stage_is_null() helper won't work.

In order to implement VK_KHR_pipeline_binary, we need to be able to
build hash from pipeline creation structures without looking at the
cache.
The blake3 hash on precomp shaders prevents that as its loading from
cache and potentially apply transformation to NIR.
Let's stick to the hash generated by vk_pipeline_hash_shader_stage(),
it does not look at NIR (except for internal shaders) and already hash
the same information :
* shader code (SPIR-V, identifier, hash)
* robustness state
* specialization constants
* pipeline flags
* entry point name
* subgroup information

Following bc64ea2815 ("vulkan: fix shader linking with common
pipelines") we're always linking pre-rasterization shaders together
and the shader hashes are hashed together, so there is no point
hashing :
- a bitfield of active shaders
- merged tesselation information

Panvk calls pan_preprocess_nir() from its preprocess hook that it hands
off to the Vulkan pipeline code. That hook gets called before we have
the opportunity to lower geometry shaders. This means that we get our
viewports lowered for the VS and then the geometry shader is trying to
work on lowered viewports, which is wrong. Instead, we want to lower
later and only apply the viewport transform in the shader that runs as
the hardware VS.

This is more robust because it ensures that we only ever check the
location on something that we know is an outupt. Also, if it's an
output then we know (thanks, validation!) that it's a variable.

While we're here, make the variable handling a little more robust by
checking the deref mode before assuming there's a reachable variable.

The comment explicitly calls out pan_nir_lower_store_component(), which
is in a different function call so it's a bit weird to have it in the
caller. Also, we already do this in postprocess() on midgard so it
makes more sense to just move it into bifrost.

Every caller of pan_shader_lower_texture() immediatly called
pan_shader_postprocess() and every caller of pan_shader_postprocess()
lowered textures except blend shaders and those don't texture anyway.

This started failing at some point between a35a12dd38 and 2f7b1e8453,
but the nightly CI was out for a long time in between, so it's hard to
tell what commit it to blame without bisecting. I'm going to leave that
up to someone else for now.
To complicate things further, it seems like this one only fails in the
nightly runs, but not in pre-merge. So we list it as a flake instead of
a consisten failure.

These are helper instructions for the spill_preserved pass to insert
reloads for registers that are preserved by the ABI, yet
clobbered by the callee shader.
There is one p_reload_preserved instruction at the end of each block.
This allows us to insert reloads early, to alleviate the high latency of
scratch reloads.

For intra only we need to allocate internal dpb.
This was previously implemented for VP9 decode only, using a buffer.
Change it to image so that we don't have to handle it as special
case everywhere.
