Follow FreeBSD 11's sys_mincore by rounding unaligned address down to page boundary rather than returning EINVAL. Update guest memory test and document unmodeled residency/referenced/modified bits in libkernel technical debt.
Implement mincore (+hFjyohmOU0) in libkernel following FreeBSD 11's sys_mincore (sys/vm/vm_mmap.c). Validate page alignment, return EFAULT for null vector, check range bounds and residency via sceKernelVirtualQuery, and report MINCORE_INCORE (1) for resident pages. Required by Java 25 LAN / DNS (PPSA99869).
agc_driver_waterfall_images fails on main since fd438f663: its compute shader
runs an LOD query with a local size of 8x1, and the module gets
DerivativeGroupQuadsKHR, which SPIR-V validation rejects unless both
dimensions are even (VUID-StandaloneSpirv-DerivativeGroupQuadsKHR-10151).
This reverts commit fd438f663, reversing changes made to 51031742e.

sceCesUcsProfileInitEucJpCp51932 returns a profile for EUC-JP, and
sceCesMbcsUcsContextInit now keeps the profile in the context. The
multibyte string conversions (UTF-8, UCS-2, their length queries) and
sceCesEucJpToUcs2 convert ASCII and the JIS X 0201 half-width katakana
for that profile, and every character for the existing CP1252/CP1251
profiles. Two- and three-byte JIS X 0208/0212 characters throw, since
their mapping table is not present.
Metal Gear Solid 4 Master Collection (PPSA18194) imports the set in its
game executable, which fails to load without it.

Every address-based build copied the cached address space's imported
ranges (about 9000 in Sword of the Sea gameplay) into its batch as pending
reads, only for the copy HLE's reader check to scan them. The space now
builds that list once, and a build that took the space whole notes it by
reference (Recorder::NotePendingReadList); its own ranges follow as before.
The space is immutable while its serial lives, the list equals the space's
part of InPlaceReads in its order, and the batch scans plain reads and lists
in note order, a list by bisection, so every PendingReadOverlaps and
DescribePendingRead answer and reader kind stay the same. A capture trace or
APS5_FLIP_READ_CHECK expands the list as before.
Tests: lists noted by reference answer like the same ranges noted one by one
(open and in-flight scans, kinds, a list noted twice, empty and null lists);
the space's list is shared while the registry stands and rebuilt when a range
is added or removed.

With batch ids in the trace, the digest gains a Largest GPU batches
section: for the longest GPU batch slices, the GPU ranges inside each and
the CPU slices carrying the same batch id, inclusive. --json carries it as
largest_gpu_batches. Traces without batch ids are digested as before.
The stream copy kernel is matched by its 16 code words instead of a hash, and the
match and its range checks become free functions (MatchesStreamCopyKernel,
StreamCopyRange) so a test can reach them. Its loads and stores are format
instructions, so the match also requires the descriptor the pattern fill takes:
32_32_32_32_UINT, XYZW selects, no add-tid, out-of-bounds mode 0, type 0. Copy
paths are counted in copyPathCounts whether or not APS5_PROFILE_DRAW is set.
agc_driver_stream_copy checks the match against every word with a bit flipped,
the descriptor and dispatch refusals, the range clamp and refusals, and runs nine
dispatches through the driver: four must take the HLE path and copy elements
g*128+t and g*128+64+t, five must be refused for their shape and leave the
shader's result.
A device that supports VK_EXT_device_fault reports, on the first
VK_ERROR_DEVICE_LOST a check sees, the fault description, the faulting
addresses (invalid reads and writes, or the instruction pointers of waves
still running when the device hung) and the vendor fault codes.
APS5_GPU_CHECKPOINTS=1 records a VK_NV_device_diagnostic_checkpoints
marker with the program address before each guest dispatch and prints the
last markers the GPU reached, which names the dispatch that hung. Without
either extension nothing changes.
Test: agc_device_fault drives the report through mock
vkGetDeviceFaultInfoEXT and vkGetQueueCheckpointDataNV entry points.
