// Default-hi slice of a slice/str FIELD (`x.f[:]`, `x.f[2:]`) —
// expression position. The pre-fix default-hi dispatch was
// N_IDENT-gated on BOTH stages, so an N_DOT base fell to MOVQ $0
// (len 0 / negative, byteid-blind). Covers local, viaptr, dot-chain,
// (*p) spelling, and struct-array-element inners.
