The recorder took its ranges once, at the snapshot, so a title that
committed memory during the captured frames replayed submissions from
memory the capture never had. Each memory delta now adds the allocations
the registry gained since the last one as new ranges with their nonzero
64 KiB blocks, and the header counts them as late_ranges.
A submission ended a captured frame when the driver's flip count changed
while it was being submitted, and the count was global, so a submission
that overlapped another thread's flipping one ended the frame as well.
The count is now kept per thread.
agc_driver_frame_replay copies its second frame from a block committed
during the capture, and agc_driver_frame_capture_eop checks that a flip
submitted on another thread leaves this thread's count unchanged; both
fail without the fix.

- Order memory deltas and video output registration before the next
recorded call, and serialize the deadlock breaker with delta application
- Capture the blocks holding shader code with each shader delta
- Reserve explicit and automatic EOP flip tokens under one lock
- Record video output unregistration so replay can close and reopen a handle
- Clear already mapped ranges before restoring the snapshot so elided zero
blocks replay as zero

An EOP flip reservation also ended a frame, and so did the submission
whose EOP release carries the reserved token, so a title flipping with
EOP releases counted each displayed frame twice: a capture of N frames
stopped after about N/2 and could start between the reservation and
the submission that flips. The reservation is now only recorded; a
frame ends at a CPU flip or at a submission that flips.
agc_driver_frame_capture_eop reserves and submits six EOP flips with
APS5_FRAME_CAPTURE_FRAMES=3 and checks that the capture starts after
the first flipping submission and holds three frames of one reservation
and one submission each.

APS5_FRAME_CAPTURE=<dir> makes the AGC driver record a few frames of a
title: the shader registrations and ABI resolutions, video output and
EOP flip reservations it made since it started, a snapshot of every
readable guest allocation (the title image included) taken at a frame
boundary once the driver is idle, and for the next frames each
submission, flip and suspend point with the thread that made it, its
serial progress and the guest pages the write tracker saw the CPU write
before it. At the end it stores the presented display buffers as
reference images. APS5_FRAME_CAPTURE_AT_FLIP, _TRIGGER and _FRAMES pick
the frames.
agc_frame_replay maps the captured memory at its addresses and replays
the calls of each captured thread on a thread of its own, in captured
order, through the current build of the driver with no title running.
It paces GPU work to the in-flight depth the title had, releases GPU
waits that the title's CPU threads released without calling the driver
(AgcDriverAwaitedWaits), and reports frame times, released waits and
how closely the replayed display buffers match the references.
Tests: agc_frame_capture (file format) and agc_driver_frame_replay
(two captured frames of CPU writes and DMA copies replayed and
compared). Docs: BUILD.md, ENVIRONMENT.md and the libSceAgcDriver debt
file.

Implement sceCesUcsProfileInitGb18030_2000 and sceCesUcsProfileInitGb18030_2005.
Two-byte cells are the CP936 table plus the cells that differ, and four-byte
sequences are runs over the BMP and the supplementary planes, generated from
ICU's gb-18030-2000.ucm (before ICU-8427) and gb-18030-2005.ucm with ICU's
GB 18030 ranges. The GB, MBC and MBCS string conversions accept both profiles
and produce four-byte UTF-8 and surrogate pairs for supplementary characters.
Since #6291 a pixel shader's EXEC copy is read as the saved word ANDed
with WQM(Ballot(true)). MaskReplaySafety only accepts a whole-quad
expansion of a ballot it can show excludes helper lanes, and a ballot
of true includes them, so a stencil-exporting shader whose own-lane
masks come from an EXEC copy was refused (own-lane mask not stable).
Every lane of a quad is active (real or helper), so a ballot of true
holds the same quad bits as the all-ones mask the proof already treats
as quad-stable; it is now classified the same way. Helper-dependent
ballots stay uncertain.

The merge resolution had dropped its storage image sentences, which main keeps and this branch does not change.

Table T#s keyed at runtime no longer fault on image_atomic_*32: the
table operation stays supported, elements carry the atomic flag through
dedup into the descriptor binding, and the table path binds AtomicView
like the direct path. 64-bit atomics stay unsupported, packed and BY
formats stay unsupported, and the debt entry records the relaxed
Device-scoped emission and the remaining gaps.
Copy the source array into this and return this, as the console does
(measured on a PS4 Pro, firmware 10.71). Knowledge is Power: Decades
imports it; the inventory stub threw NotImplemented.
