The draw key mixed all 32 user data words of every stage. It now mixes only the
words a stage's RSRC2 counts, so draws that differ only in words their programs
never read share an entry. The RSRC2 registers stay in the key.
APS5_DRAW_KEY_ALL_USER_WORDS=1 mixes all 32 again.

A0-A3 (MOV AL/eAX/rAX to and from moffs) have no ModRM byte and carry an
8-byte absolute address in 64-bit mode, or 4 bytes with a 0x67 prefix.
The decoder added nothing for the address, so the linear scanner decoded
the address bytes as code.

The Linux patcher appends the DT_RUNPATH string after the copied
.dynstr data but kept DT_STRSZ and the .dynstr section size at the size
of the copied data, so DT_RUNPATH pointed at the first byte past the
declared string table.

In 64-bit mode REX.W takes precedence over the 0x66 operand-size prefix,
so the immediate of 81, C7, 69, 68, A9, the 05..3D accumulator forms and
the F7 TEST form stays imm32. The decoder only applied this to B8+r and
returned a length two bytes short for the others.

PPSA01325 stops on sceFontGlyphDefineAttribute right after generating a character glyph: it sets attribute 0x11 to 0 on that glyph, deletes it without using it, and draws the character with sceFontRenderCharGlyphImageHorizontal. The meaning of the attributes is unknown, so the call checks the glyph and ignores the rest; TechnicalDebt lists it under silent stubs.

Astro's Playroom (PPSA01325) fails eager binding on three imports. The two voice chat group requests follow the offline model of the other sceVoiceChatRequest* calls and return SIGNED_OUT; sceRudpActivate, whose signature is unknown, is declared as a throwing stub.

IMAGE_LOAD_PCK2/PCK4, IMAGE_LOAD_MIP_PCK2/PCK4, IMAGE_STORE_PCK2/PCK4 and
IMAGE_STORE_MIP_PCK2/PCK4 are separate MIMG opcodes (112/113, 115/116,
118/119, 121/122 on RDNA1 and RDNA2 in AMD's generated tables), not dmask
forms of IMAGE_LOAD_PCK (2), IMAGE_LOAD_MIP_PCK (4), IMAGE_STORE_PCK (10)
and IMAGE_STORE_MIP_PCK (11). The decoder has no entries for them and
throws "unsupported MIMG opcode", so they are no longer credited.

Recorder::KeepDrawSnapshot keeps nothing larger than the pool's byte
budget, and the storage-buffer pool's budget was 256 MiB (the draw
input pool, for vertex and index data, has 1 GiB). A read-only storage
buffer a draw reads in place from an import is copied into a snapshot
per draw; one larger than 256 MiB was never kept, so every draw copied
it again even when the guest had not touched it.
PPSA14632 (LEGO Horizon Adventures) binds a 576 MiB direct-memory buffer
to many draws: each one memcpy'd all 576 MiB (about 100 ms), 176 times
in 60 s. With the budget at 1 GiB, as for draw inputs, the snapshot is
reused while the buffer is unchanged (394 reuses and 41 copies in 90 s),
and Graphics::Draw drops from about 7 ms to 1 ms per draw packet.

Add header-only support for end-to-end relinker tests: a minimal PS5
executable builder, a PT_LOAD mapper that applies segment permissions,
and a posix_spawn runner for the relinker binary. Every
core/relinker/tests/e2e/*.cpp becomes its own test, so new tests do not
touch CMake.
The first test relinks an executable with EXTRQ and INSERTQ sites using
--to-intel, maps the output and calls the patched code, which runs both
stubs from their Linux segment and returns through their branches.

On Linux ngs2_atrac9 aborted without any output once TestParseFile was part of
its main(). The exception that TestCorruptSuperframeAtPageEnd throws in the
Ngs2 module and catches in main() has to resume through a cleanup landing pad
inside main(). That resume goes through the unwinder statically linked into the
test executable, which then fails with _URC_FATAL_PHASE2_ERROR and aborts
silently. Whether main() gets such a pad depends on what the compiler inlines
into it, so adding any function with non-trivial cleanups to that main() is
enough to trigger it.
Move the PCM and file parse tests into a new ngs2_parse executable and restore
Ngs2Atrac9.cpp to its upstream content, so the test that catches exceptions is
unchanged. The new executable has no catch and never relies on that path.
