It is an improved version of etna_drm_screen_create_renderonly(..)
which also needs the gpu fd. Also switch etna_drm_screen_create(..)
and etna_drm_screen_create_renderonly(..) to use the new function.
This follows how other driver's winsys code looks like and fixes a
crash I when running piglit with PIGLIT_PLATFORM="gbm".

There are exceptions in spec where the framebuffer image format and
format given for render pass attachment may differ. This happens in
particular when subpass has resolve attachment that might resolve
only depth from a combined depth+stencil format. There the formats do
not need to match but be 'compatible' with each other.
As example using VK_FORMAT_D32_SFLOAT format is considered compatible
when actual framebuffer format is VK_FORMAT_D32_SFLOAT_S8_UINT.

The previous code checked for element containment first and then performed
another map lookup upon element access. Instead, map::find can be used to
retrieve an iterator usable for element access with no extra lookup needed.
Furthermore, pure containment checks have been simplified using map::count.

While adding/removing elements is faster with std::map, the cost of container
copies (and the involved memory allocations) vastly outweigh that benefit in
this usage pattern.

Recreating these maps in a later block requires allocating fresh memory.
Instead, by never shrinking the containing vector in the first place,
previously allocated map memory is now re-used.

The function local_next_uses allocated one next-use map per instruction in
the current block. Since the function is called once per block, this caused
an excessive amount of memory allocations to take place.
With this change, the memory for next-use maps is allocated only once and
then reused for later blocks.

By default, std::stack uses std::deque to allocate its elements, which has
poor cache efficiency. std::vector makes appending elements more expensive
(due to potential reallocations), but in the changed contexts the element
count should always be low anyway.

Now that ACO is considered feature-complete, it can be nice to avoid the
huge LLVM dependency when one only wants a Vulkan driver.
This patch allows radv to be built without LLVM. The two features which
get disabled are RADV_DEBUG=llvm and shader disassembly. The latter
is an issue for debugging, so I added a warning that this configuration
is unsupported.

ACO relies on LLVM to disassemble AMD shaders for ISAs newer than GFX7,
so disassembly needs to be skipped when LLVM is not enabled.
For vkGetPipelineExecutableInternalRepresentationsKHR and vkGetShaderInfoAMD,
the disassembly will not be reported anymore if it can't be generated.

With all the preparation in place to handle suballocated BOs at
submission and export, we can now wire up the actual suballocator.
We use Gallium's pb_slab infrastructure for this, which is already
used for this purpose in the amdgpu winsys and now zink as well.
Unlike those drivers, we don't use pb_buffer (it doesn't do much) nor
pb_cache (we already have a buffer cache). Just pb_slab for now.
We can now suballocate BOs at power-of-two (or 3/4 power-of-two)
granularity, between 256B and 2MB. Beyond that, we use actual GEM
objects as before. This should save us some memory on current GPUs
where we previously had a minimum allocation granularity of 4K (page
size), but should save us a /ton/ of memory on future GPUs where the
minimum page size is 64K. Fewer actual GEM objects should also mean
shorter exec_object2 lists passed to the kernel, which could reduce
CPU overhead a bit. Using large allocations where the underlying
GEM objects correspond with the PTE fragment size may also allow the
kernel to use a more efficient page table layout, improving memory
access times.
This cuts nearly half of the memory usage in a Unity3D demo on a
GPU that uses 64K pages.
