(DECODE_DESIGNATION): Jump to label_invalid_code if
final_char is invalid.
(decode_coding): If coding->type is coding_type_ccl, call
ccl_coding_driver even if SRC_BYTES is zero.
(code_convert_region): Update `inserted' correctly after calling
coding->post_read_conversion. Even after the code converter
consumed all source text, call it once more if it is
coding_type_ccl to flush out data.
