builtin_islessgreater_unordered.wasm.skip (250B)
1 wasm re-lowering of the discriminating FP predicates (ONE / unordered duals) is not yet NaN-correct on the foundation; same gap fails the untouched rv64_fp_nan_compare on lane W (got 4 at ne_d). Tracked separately from the C-frontend Route A/B work.
