Reimplement the five synthetic regressions from codefusion-repo/sharpemu#3 and #8 on sharpemu/sharpemu main befd20f415.
Keep the contributor-owned harness and corpus discussed in sharpemu/sharpemu#36 out of scope; use only a focused local recording memory fixture.

Adds decode and SPIR-V translation for the missing MUBUF, MIMG and DS
atomic instructions in the Gen5 shader translator, generalizing the
existing BufferAtomicAdd path. Covers swap, cmpswap, add, sub,
smin/smax, umin/umax, and/or/xor, inc and dec, plus the DS RTN
variants. Image atomics go through OpImageTexelPointer on the storage
image binding.
Notable: DS_CMPST operand order (DATA0 = comparator, DATA1 = new
value) is reversed relative to buffer/image cmpswap, which a dedicated
test locks in. ATOMIC_INC/DEC are approximated with
OpAtomicIIncrement/IDecrement, exact for the common 0xFFFFFFFF clamp.
Verified with 9 new synthetic decoder and end-to-end SPIR-V tests
(part of the #36 test corpus effort); full suite passes 35/35.

* [HLE] Trigger AGC graphics events by filter instead of exact ident (#173)
The PM4 EVENT_WRITE packet carries a 6-bit hardware EVENT_TYPE, but the
guest registers AGC events via sceAgcDriverAddEqEvent with a full guest
eventId. These two values are not the same numbering scheme, so the exact
ident lookup in TriggerRegisteredEvents never matched and the AGC
interrupt thread hung forever.
Add TriggerRegisteredEventsByFilter, which wakes every graphics event
registration on every queue. This is a compatibility workaround for
issue #173 while the real PS5 mapping remains unknown.
Includes unit tests covering the mismatched ident/eventType case.
* [HLE] Fix POSIX condition variable semantics (#113)
Remove PendingSignals from PthreadCondState. POSIX condition signals are edges,
not semaphore credits - a signal with no waiter must have no effect. The previous
implementation persisted signals, causing lock inversions and predicate bypasses.
Changes:
- Remove PendingSignals property and TryConsumePendingSignal method
- Remove pending signal consumption logic from PthreadCondWaitCore
- Remove PendingSignals increment from PthreadCondSignalCore
- Add regression tests verifying POSIX-correct behavior
Fixes#113
