As that handles better, and more clear, the case of bindingCount being

This makes UBO loads in the variable pointers or bindless case work just
like SSBO loads in the sense that they use A64 messages and 64-bit
global addresses. The primary difference is that we have an
optimization in anv_nir_lower_ubo_loads which uses a (possibly
predicated) block load message when the offset is constant so we get
roughly the same performance as we would from plumbing load_ubo all the
way to the back-end.

Instead of allocating a push constant buffer per stage from the

We can do this because the push constant data is supposed to be
identical of all stages. Even if vkCmdPushConstants() allows to update

In 105002bd2d, we fixed a memory leak bug where we weren't properly
destroying descriptor when destroying/resetting a descriptor pool.
However, the only real leak that happened was that we we take a
reference to the descriptor set layout in the descriptor set and we
weren't dropping our reference. Everything else in the descriptor set
is tied to the pool itself and doesn't need to be freed on a per-set
basis. This commit changes the destroy/reset functions to only bother
walking the list of sets to unref the layouts and otherwise we just
assume that the whole-pool destroy/reset takes care of the rest.
Now that we're doing more non-trivial things with descriptor sets such
as allocating things with util_vma_heap, per-set destruction is starting
to show up on perf traces. This takes reset back to where it's supposed
to be as a cheap whole-pool operation.

In c520f4dec9, we chose to align the sizes of descriptor set buffers to
32 bytes. We have to align the descriptor set buffer to 32B so that
it's valid for using with push constants. We align the size as well so
we don't leave lots of holes with util_vma_heap_alloc. Unfortunately,
we were only aligning it for alloc and not for free so we were still
creating piles of holes when we delete descriptor sets. This causes
terrible perf for the allocator once we've deleted piles of descriptor
sets.
This commit reworks the code so that we align the descriptor set buffer
size to 32B for both alloc and free. The result is that it takes the
new crucible vkResetDescriptorPool from 104.567719 to 2.898354 seconds.
