    Implement list-initialization of _Complex.
    * decl.c (reshape_init_r): Allow {real,imag} for _Complex.
    (check_initializer): Likewise.
    * call.c (build_complex_conv): New.
    (implicit_conversion): Call it.
    (convert_like_real): Handle it.
    * typeck2.c (check_narrowing): Handle it.
