Nahid DelicandClaude Opus 5.5 7e4ce1ab3d fix(shader): act on the containing dword for unaligned 32-bit buffer atomics ...

The RDNA2 ISA (8.1.7) ignores the two low address bits of dword or wider
non-formatted accesses in alignment mode DWORD. MXGP 26 (PPSA30839) sets
bits with buffer_atomic_or at odd byte offsets, which recorded an
unaligned BDA fault and dropped the atomic. A 32-bit buffer atomic now
acts on the dword that holds its address; 64-bit atomics off an 8-byte
boundary still fault.
