shader: lower warp reductions, shared atomics and descriptor loads
Compute forms Fire Emblem: Fortune's Weave uses:
- REDUX.OR and REDUX.MIN (unsigned), next to SUM and MAX. Inactive lanes
give the identity (all ones for MIN).
- ATOMS.MIN, MAX and OR (U32); the native operation field numbers them
as Maxwell's.
- LDG with desc[URn][Ra.64] addressing: the uniform pair is a memory
descriptor (cache policy), so Ra alone is the address.
- BAR.SYNC.DEFER_BLOCKING (bit 80), the usual workgroup barrier.
Assisted-by: Claude Opus 5.5 (debugging, implementation and drafting)
