The resource materializer refused every atomic image descriptor whose
format was not 32_UINT. RDNA2 image atomics act on the raw dword and
the numeric format only affects addressing, so 32_SINT and 32_FLOAT
surfaces are now accepted with the Uint numeric class and run through
the existing integer atomics and float compare-exchange loops. Other
formats still throw, and the message now names the format.
DescriptorBinding gains imageAtomic, carried through the shader disk
cache (format version 4) and the resource content key. The driver
binds those elements through a cached R32_UINT view of R32_SINT and
R32_SFLOAT storage images.

AMD hardware compares a sample_c reference against a color texture's red
channel; Vulkan defines comparison sampling only for depth formats, so the
driver refused any compare-sampled texture that is not R32 float or R16
unorm. PPSA21567 compares the same LESSEQUAL, clamp-to-border (opaque
white) sampler against a shadow map and against a 1x1 RGBA8 texture.
For a compare-sampled image whose format is not natively comparable, the
specialization records the paired sampler's compare function, filter,
addressing and border, and the view's reference clamp kind; the image then
binds as an ordinary color texture. The backend fetches the red channel,
applies wrap, clamp-to-edge or clamp-to-border addressing with the
sampler's texel-centre convention (border taps take the border's red),
compares, and blends four comparisons for bilinear filtering. Real depth
formats keep the native path.
Only sample_c / sample_c_lz on 2D and 2D array views, float/unorm/snorm
formats, wrap, clamp-to-edge or clamp-to-border, point or bilinear at one
level are implemented; half-border, the border color table and everything
else on this path throw. The reference clamp for unorm/snorm color formats
is not documented by AMD and is recorded in the technical debt.

Write the raw texel bits: dmask bit i selects texel dword i, taken from the
next data register, and every other dword of the texel is written as 0; the
descriptor swizzle is ignored (measured on RDNA2 hardware). Only formats whose
bits go through the storage view unchanged are accepted (unsigned integer
components, raw 32-bit signed integer and 32-bit float); normalized, 16-bit
float, narrow signed and 96-bit formats throw.

Return the raw texel bits: dmask bit i selects texel dword i, dwords past the
texel read 0 and the _sgn forms sign-extend texels narrower than 32 bits
(measured on RDNA2 hardware). Only formats whose bits are exactly recoverable
from the sampled view are accepted (unsigned/signed integer, unorm up to 16
bits, 32-bit float components), on a direct sampled image with identity
swizzle; anything else throws.

Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

A V# with records but a base address of 0 threw at bind time ("null shader
buffer descriptor address"), although a shader that never reaches that slot
works on hardware; an access through it would fault there, so a working
title does not make one.
Such a V# is specialized empty like one without records (every access out of
bounds) and binds the placeholder buffer; the draw cache's alias check skips
it as the build does. The tests expecting the old rejections are dropped.

A V# without records (all zero, say, for a slot the taken path never
uses) makes every access out of bounds on hardware: loads read zero or the
format's default, stores and atomics are dropped. The recompiler now
specializes such a buffer as empty, so every access through it is out of
bounds, and the driver binds a small per-device placeholder buffer to the
element instead of rejecting the V#. A V# with records at address zero
still throws.

A sampled T# of a 32-bit integer format over a depth layout (a Z swizzle
mode) reads the raw bits of a depth plane, and a host cannot view a depth
image with an integer format. Such an image is specialized as float and
bound as the depth surface's float view: a fetch returns the same bits,
which the shader keeps as they are, and swizzle constants read as the
integers 0 and 1. Filtering is forced to point, as for integer formats.
The same T# over guest memory rather than a depth surface throws.

Dispatch cache with per-key value variants and data-only hits (flat-SRT leaves the recompiler
proves pure are refreshed into the resource template instead of re-captured), dispatch and draw
recipes replaying a proven prepare, register-keyed draw entries, template data refresh, unit
shadows in device-local slabs, 64 KiB block-unit storage tracking with windowed detile, DCC
clear-key proofs, per-class GPU timing, a CPU copy path with batch read tracking, present slot
ring, rate-limited reaps and lazy completion counting, plan-failure and poisoned source memos,
bindless image tables (runtime-indexed descriptor arrays from a CPU-read table) so the
per-frame compute program that failed its plan now compiles. Worker affinity opt-in, per-draw
logs behind APS5_TRACE_DRAWS, wait-timeout reports include the recorder's view of the label.
Fixes a use-after-free behind BDA-miss dispatch snapshots and the CPU-write stamp of
UnchangedSinceCollected. Intro-video stage: 154 -> ~500 presents per 10 s at 4K.
