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.
