Jason Ekstrand baf4802e3e anv: Better handle 32-byte alignment of descriptor set buffers 
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.

Fixes: c520f4dec9 "anv: Add a concept of a descriptor buffer"

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.html
<https://mesa3d.org/install.html>`_), but the recommended way is to use

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
