radv: implement VK_KHR_push_descriptor

radv: replace an assertion with a conditional

Replace the !binding_layout->immutable_samplers assertion in
radv_update_descriptor_sets with a conditional.

The Vulkan specification does not say that it is illegal to update
a sampler descriptor when it is immutable; only that pImageInfo is
ignored.

This change is also needed for push descriptors, because valid
descriptors must be pushed for all bindings accessed by shaders,
including immutable sampler descriptors.

radv: refactor radv_UpdateDescriptorSets

Move the implementation into a separate function that takes a
cmd_buffer and a dstSetOverride parameter.

When cmd_buffer is not NULL, radv_update_descriptor_sets calls
cs_add_buffer directly instead of updating the buffer list.

This will be used to implement VK_KHR_push_descriptor.

anv/query: Busy-wait for available query entries

Before, we were just looking at whether or not the user wanted us to
wait and waiting on the BO.  Some clients, such as the Serious engine,
use a single query pool for hundreds of individual query results where
the writes for those queries may be split across several command
buffers.  In this scenario, the individual query we're looking for may
become available long before the BO is idle so waiting on the query pool
BO to be finished is wasteful. This commit makes us instead busy-loop on
each query until it's available.

This significantly reduces pipeline bubbles and improves performance of
The Talos Principle on medium settings (where the GPU isn't overloaded
with drawing) by around 20% on my SkyLake gt4.

anv: Advertise larger heap sizes

Instead of just advertising the aperture size, we do something more
intelligent.  On systems with a full 48-bit PPGTT, we can address 100%
of the available system RAM from the GPU.  In order to keep clients from
burning 100% of your available RAM for graphics resources, we have a
nice little heuristic (which has received exactly zero tuning) to keep
things under a reasonable level of control.

anv: Add support for 48-bit addresses

This commit adds support for using the full 48-bit address space on
Broadwell and newer hardware.  Thanks to certain limitations, not all
objects can be placed above the 32-bit boundary.  In particular, general
and state base address need to live within 32 bits.  (See also
Wa32bitGeneralStateOffset and Wa32bitInstructionBaseOffset.)  In order
to handle this, we add a supports_48bit_address field to anv_bo and only
set EXEC_OBJECT_SUPPORTS_48B_ADDRESS if that bit is set.  We set the bit
for all client-allocated memory objects but leave it false for
driver-allocated objects.  While this is more conservative than needed,
all driver allocations should easily fit in the first 32 bits of address
space and keeps things simple because we don't have to think about
whether or not any given one of our allocation data structures will be
used in a 48-bit-unsafe way.
