Combines this branch's sample order with #6470's once-per-pixel and once-per-sample inputs. The pixel request keeps both sides' fields: #6470's iteration, position location and sample locations are serialized at version 34, and the sample order after them at version 35. The serialization tests move the sample-order bytes after the iteration fields and drop both from older versions. The pixel info collector adds sample order to the SampleLocationsVary inputs, and the draw keys compare and hash both. EmitSampleOffset's iterated index already goes through GuestSampleIndex, since the SampleId builtin does. The shader cache stays at FormatVersion 40, and the sample-location debt entry takes #6470's sentence on the position inputs.
The custom MSAA sample-location debt entry keeps this branch's grid stand-in text and takes main's sentence on ANCILLARY and the position inputs of a once-per-pixel shader.
A vertex-path program with LDS, GDS or memory writes refused any s_barrier. NGG passthrough
programs start with the s_barrier that orders GS_ALLOC_REQ, before any memory access, and some
write buffers later. A barrier that runs before every load, store, atomic, image or LDS access of
the program has nothing to order, so it emits no instruction, like the barrier of a program
without memory access. Barriers after a memory access still throw.

Write the INDEX_ATTRIBUTES_INDIRECT packet the console's builder writes,
as measured by the prosper console oracle, with OpenAGC's signature, and
report its measured size of 16 bytes.

The data-hit verification keeps this branch's pending-span query on its ShaderMemory and takes #5958's CaptureInvocation, which retries a capture with converted samples.
Keeps this branch's tagVariantRuns declaration next to main's dumpRequest suffix parameter in Driver.hpp, and reads #6232's pointer-chain test words from its table's snapshot, where this branch keeps them.
A shared mapping is a view of a file section created on the descriptor's
handle, read-write when the descriptor is, otherwise read-only. A private
mapping is a copy of the file read at mmap, as POSIX allows. Anonymous
shm_open objects and JIT shared memory descriptors are temporary files on
Windows, so mmap now maps them too (it failed with EOPNOTSUPP before).
mprotect of a mapped view above the view's protection fails with EACCES
before any bookkeeping changes. The cases Windows cannot represent are
listed in the libkernel debt.
Dusklight (PPSA99305) uses SQLite in WAL mode, which maps its -shm file.
On Windows main f0634088b every start logged "Failed to start
transaction: disk I/O error" for its Dawn and pipeline caches (3 of 3
runs); with this change the caches initialise and their WAL files fill
(4 of 4 runs). The title reaches its menu either way.
A shared mapping may end inside the 16 KiB page that holds the end of
the file, as POSIX mmap allows: the view ends with the file's last 4 KiB
host page, which Windows zero-fills past the end, the rest of the guest
page is private zero pages, and the file never grows. A mapping that
reaches a whole page past the end still fails with EOPNOTSUPP.
PS5LM Plus (PPSA99581) loads its model with llama.cpp, which maps the
whole GGUF file shared and read-only. With a 491,400,032-byte model,
Windows main 5de7a46e0 and this change without the last page logged
"llama_model_load: error loading model: mmap failed: Operation not
supported" (3 of 3 runs); now the model loads and the completion of
"The capital of France is" starts with " Paris" (3 of 3 runs).

Takes #6215's framebuffer owners and target-owned sampled textures, keeping this branch's sample-order steps after the framebuffer and the sampled-only usage next to the storage order view.
The 1-, 2- and 8-byte loads, stores, exchanges, compare-exchanges and fetch
operations, _Atomic_is_lock_free_N, the flag and fence functions and the
lock-based generic _Atomic_copy, _Atomic_exchange and _Atomic_compare_exchange_*,
matching the libc.prx bundled with PPSA08427 including its handling of
invalid memory orders.
