blorp: add blorp string in shader keys

Upon looking at caching the raytracing shader (in particular the
trampoline one) I kind of got afraid that some of the keys used for
blorp would end up matching other keys. This is because blorp keys are
fairly simple. There is no SPIRV module hash included.

This change includes a "blorp" string at the beginning of the queue to
ensure we don't collide with other keys.

anv: Compile ray-tracing shaders

This doesn't look too different from other compile functions we have in
anv_pipeline.c.  The primary difference is that ray-tracing pipelines
have this weird two-stage thing where you have "stages" which are
individual shaders and "groups" which are sort of mini pipelines that
are used to handle hits.  For any given ray intersection, only the hit
and intersection shaders from the same group get used together.  You
can't have an intersection shader from group A used with an any-hit from
group B.  This results in a weird two-step compile.

crocus/gen8: limit some pipe controls to gen7/hsw

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11507>

crocus: refactor blend state code.

This just refactors this code before adding gen8 support which
needs more changes in this area.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11507>

crocus: convert a bunch of is_haswell into verx10 checks.

This just make things easier when gen8 support is added

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11507>

crocus: fixup workaround_bo to match 965.

Always add to the batch, and don't set the reloc write flag when
adding to reloc list, as this will confuse the render/compute sync
code and cause over syncing.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11507>

crocus: rename genX proto functions to avoid iris conflicts.

If we start adding gen8, then conflicts occur, but the crocus
ones into their own namespace to avoid this.

crocus: fixup stray tab

crocus: drop dead gen prototypes.

i915g: Clear xfails for vertex texturing.

Fixes: 7378c6479278 ("i915: Disable vertex texturing and delete the code.")
Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Use the color swizzle to reshuffle the blend const color.

If we're remapping RGBA from the shader into dst channels, we also need to
remap the blend constant color.  The previous static mapping only worked
for ARGB cbufs, but we get ABGR in surfaceless deqp.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Simplify color write mask setup.

Use the surface's precomputed swizzle instead of doing a local format
table.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Move cbuf color swizzle lookup to CSO creation time.

Saves walking the loop, and makes a nice place to store a swizzle for use
in other atoms.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Compute 3DSTATE_BUF_INFO flags at surface create time.

No need to compute them at state emit.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Create an i915_surface for our pipe_surfaces.

Nothing added in yet, just wrapping the struct.

Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11512>

i915g: Remove nr_cbufs loop.

This hardware definitely only does one cbuf.

radeon/vcn: use st_rps_bits only when it's set

Fixes: c9baccb5

For certain player which doesn't implement st_rps_bits, or when st_rps_bits
is set to 0 (e.g. it doesn't have rps explicitly defined in slice header),
we don't set st_rps_bits and the related flag, since we don't skip parsing
the rps structure in these cases.
