  -----------
  [MC] Ensure all new sections have a MCDataFragment

MCAssembler::layout ensures that every section has at least one
fragment, which simplifies MCAsmLayout::getSectionAddressSize (see
e73353c7201a3080851d99a16f5fe2c17f7697c6 from 2010). It's better to
ensure the condition is satisfied at create time (COFF, GOFF, Mach-O) to
simplify more fragment processing.
