Section 13.2.3. of the Vulkan spec requires that implementations be able to
bind sparsely-defined Descriptor Sets without any errors or exceptions.
When binding a descriptor set that contains a dynamic buffer binding/descriptor,
the driver attempts to dereference the descriptor's buffer_view field if it is
non-NULL. It currently segfaults on undefined descriptors as this field is never
zero-initialized. Zero undefined descriptors to avoid segfaulting. This
solution was suggested by Jason Ekstrand.

sampler views for fragment shaders, the number of samplers and sampler

It was returning true if the function types have different lengths rather
than false. This was new with the SPIR-V to NIR pass and I thought I'd
fixed it a while ago but it may have gotten lost in rebasing somewhere.

If a block might be entered from multiple locations, then the uniform
stream will (probably) be at different points, and we need to make sure
that it's pointing where we expect it to be. The kernel also enforces
that any block reading a uniform resets uniforms, to prevent reading
outside of the uniform stream by using looping.
With control flow, we can't be sure that we'll see the uses of a variable
before its def as we walk backwards. Given that NIR is eliminating our
long chains of dead code, a simple solution for now seems fine.
This slightly changes the order of some optimizations, and so an opt_vpm
happens before opt_dce, causing 3 dead MOVs to be turned into dead FMAXes
in Minecraft:
instructions in affected programs: 52 -> 54 (3.85%)
Previously, we could assume that a MOV from a temp was always an available
copy, because all temps were SSA in NIR, and their non-SSA state in QIR
was just due to the fact that they were from a bcsel or pack_unorm_4x8, so
we could use the current value of the temp after that series of QIR
instructions to define it.
However, this is no longer the case with control flow. Instead, we track
a new array of MOVs defined within the block that haven't had their source
or dest killed yet, and use that primarily. We fall back to looking
through the QIR defs array to handle across-block MOVs, but now require
that copies from the SSA defs have an SSA src as well.

According to HSW's PRM, vol02b, the DIM instruction has the following
restriction:
"Restriction : src0 must be immediate. src0 must specify the :f (F, Float)
type encoding but is an immediate 64-bit DF (Double Float) value. dst
must have type DF."
This commit allows to upload the immediate 64-bit DF value to the source
of a DIM instruction even when it is of float type encoding.

This reverts commit d8d6091a84.
Heap allocations may be only 8-byte aligned on 32-bit system, and so having
members with 16-byte alignment (such as in the case where pipe_blend_color is
embedded in radeonsi's si_context) is undefined behavior which indeed causes
crashes when compiled with gcc -O3.

This is based on a very long set of discussions between Chad and myself
about how we should properly represent HiZ and CCS buffers. The end result
of that discussion was that a tiling actually has two different sizes, a
logical size in elements, and a physical size in bytes and rows. This
commit reworks ISL's pitch and size calculations to work in terms of these
two sizes.

I have no idea why we were multiplying by 4 before. The offsets we get
from SPIR-V are in bytes and so is nir->num_uniforms so there's no need to
