If the size here is not a multiple of the granularity (64kb) then
we'll miss our "pages" estimation by 1. We could fix this with
DIV_ROUND_UP() or by simply putting a "+1" there, but the upper layers
should now be preventing this case so let's just put the assertion
here.
Previously it was possible to hit this case with Zink by running
under certain conditions piglit/arb_sparse_buffer-basic.

From the spec:
"Resources can be bound at some defined (sparse block) granularity."
"The sparse block size in bytes for sparse buffers and
fully-resident images is reported as
VkMemoryRequirements::alignment. alignment represents both the
memory alignment requirement and the binding granularity (in bytes)
for sparse resources."
Not only the upper layer (the Spec) doesn't allow this, the lower
layers (both the vm_bind ioctl and TR-TT) also work on a granularity.
Just check for this case and return an error.
Before this check, what would happen was:
- for the vm_bind backend, the vm_bind ioctl would fail
- for the TR-TT backend, we'd understimate l1_binds_capacity and
fail an assertion, or we'd just silently bind 64kb instead of the
original size
Currently, some Zink tests such as piglit/arb_sparse_buffer-basic can
trigger this behavior, but we're working to fix Zink for this case
(and that commit may be merged before this one).

A previous patch already removed individual compilation of the inputs,
by simply concatenating the files. This patch removes the linking of
the remaining single object that's compiled.

We had the unfortunate finding on a recent platform to learn that the
bindless sampler heap is not functioning as expected.
Nowhere in the documentation is the size of the heap written down. So
most people assumed that's the max number that we can program (4Gb).
The reality is that it's only 64Mb.
Though it is appearing like it's working properly for the whole 4Gb
range for most apps, this is only because the HW bounds checking
applied is broken. Instead of clamping anything beyong 64Mb, it's only
clamping the last 4Kb of each 64Mb region.
So this heap is useless for us to make a 4Gb region of both sampler &
surface states...
This change essentially turns off the bindless sampler heap on DG2+.
The only location where we can put SAMPLER_STATE elements is the
dynamic state heap. Unfortunately we cannot align the dynamic state
heap with the bindless surface state heap. So the solution is to
allocate sampler & surface states separately, each from the own heap
in the descriptor pool.
We now have to provide 2 sets of offsets for surfaces & samplers.

According to PRMs, to use self-modifying code correctly we have to
disable preparser before jumping to the generated commands, and re-enable
it with a first command in that buffer.
Old implementation did it wrong: for both inplace and inring generation
it disabled preparser before running the generation shader, had it
disabled during generation, and re-enabled it just before jumping to
the generated commands.
This usually didn't cause any trouble, because the generation shader and
generated draws are in different BOs, and the jump distance is greater than
the command FIFO depth. But we allocate them from the same pool,
so there are rare cases where the end of the BO with generation commands,
and the beginning of the BO with generated draws are adjacent. In such
cases, the wrong commands might be fetched.

Imagine 3 blocks A, B, and C. A has a physical link to B, and B has a
logical link to C. Previous to this commit, if B were removed, A would
get a logical link to C. This is not correct.
This was specifically observed to occur when block A was a DO block and
B was the WHILE block. The DO block would have two logical successors,
and that is completely invalid.
v2: Assert that the links from A-to-B and B-back-to-A are the same
kind. Suggested by Caio.
v3: Assume the successor and predecessor lists are well formed. Use this
to simplify the logic. Suggested by Caio. Add checks to cfg_t::validate
to ensure the lists are well formed.
v4: Remove (now unused) bblock_link_invalid. Suggested by Curro.

creating a physical link when a logical link already existed. However, a
logical link could be added when a physical link already existed. This
change causes an existing physical link to be "promoted" to a logical
