Assembly overrides can now declare an arm64 body for FEAT_FHM, the f16-product / f32-accumulate multiply-adds (FMLAL, FMLAL2 and their by-element forms). The base package detects it (hw.optional.arm.FEAT_FHM on darwin, HWCAP_ASIMDFHM on linux) as CPUFHM, and the dispatch ladder checks it first: the arm64 levels are independent features rather than a ladder, so the order only decides which of several present bodies runs.
