The query buffer contains a batch to implement the multi pass
replay/accumulation of results. So we can't clear it with a memset.
An optimization for later would be to move the batches to the very end
of the query buffer so we can clear the query data without touching
the batches.

Imported buffers may be created in a device with different
memory alignment and this can cause vm bind to fail because bo
size can be smaller than the calculated vm bind range using the
importer device memory alignment.
So here adding actual_size to anv_bo, this will be set with the actual
size of the bo allocated by kmd for bos allocate in the current device.
For other bo the lseek or the Vulkan API size will be used.

There's no guarantee that this is a SSA value. Use the helper to handle
both SSA values and register correctly. Otherwise we read trash when we
encounter a register and make bad decisions on types, possibly leading
to our destination being UQ typed when the VGRF is only 32-bit.

Every nir_ssa_def is part of a chain of uses, implemented with doubly linked
lists. That means each requires 2 * 64-bit = 16 bytes per def, which is
memory intensive. Together they require 32 bytes per def. Not cool.
To cut that memory use in half, we can combine the two linked lists into a
single use list that contains both regular instruction uses and if-uses. To do
this, we augment the nir_src with a boolean "is_if", and reimplement the
abstract if-uses operations on top of that list. That boolean should fit into
the padding already in nir_src so should not actually affect memory use, and in
the future we sneak it into the bottom bit of a pointer.
However, this creates a new inefficiency: now iterating over regular uses
separate from if-uses is (nominally) more expensive. It turns out virtually
every caller of nir_foreach_if_use(_safe) also calls nir_foreach_use(_safe)
immediately before, so we rewrite most of the callers to instead call a new
single `nir_foreach_use_including_if(_safe)` which predicates the logic based on
`src->is_if`. This should mitigate the performance difference.
There's a bit of churn, but this is largely a mechanical set of changes.
