  |     c++: Normalize character array initializers after folding [PR127416]
  |     
  |     The call to braced_lists_to_strings in store_init_value does not look
  |     through TARGET_EXPR. A constexpr aggregate initialized through one can
  |     therefore retain a character array CONSTRUCTOR after constant evaluation.
