To my knowledge, there's nothing in irrtoolset to do this directly.  You 
can do it indirectly by performing something like this meta shell code:

# retrieve list of ASNs in an AS-SET
peval -no-as AS-SET

# iterate through results
for i in assetresults; do
	echo -n ${i}" " && peval 'afi ipv6.unicast '${i}
done

This is slightly slow and clunky, but it should work fine.
