	* decl.cc (struct reshape_iter): Add raw_idx member.
	(cp_maybe_split_raw_data): Add inc_cur parameter, set *inc_cur,
	don't modify original CONSTRUCTOR, use d->raw_idx to track index
	into a RAW_DATA_CST d->cur->value.
	(consume_init): Adjust cp_maybe_split_raw_data caller, increment
	d->cur when cur_inc is true.
	(reshape_init_array_1): Don't modify original CONSTRUCTOR when
	handling RAW_DATA_CST d->cur->value and !reuse, instead use
	d->raw_idx to track index into RAW_DATA_CST.
	(reshape_single_init): Initialize iter.raw_idx.
	(reshape_init_class): Adjust for introduction of d->raw_idx,
	adjust cp_maybe_split_raw_data caller, do d->cur++ if inc_cur
	rather than when it returns non-NULL.

	half of _Complex earlier, also check for
	error_operand_p (d->cur->value).  Use consume_init instead of
