which preferred the domain of the stacked arrays.

967b888d8c Reduce iterations in concatenate! 
This commit should reduce the amount of iterations in concatenate to N
where N is the sum of the lengths of the input lists.

The previous implementation iterated from the beginning in each
concatenation because of `last-pair`.

This implementation is significantly faster in this extreme case:

(concatenate! `(,(iota 50000) ,@(map list (iota 500))))

>> Previous implementation:
real	0m0.671s
user	0m0.658s
sys	0m0.013s

>> This implementation:
real	0m0.175s
user	0m0.174s
sys	0m0.001s

The tests is done using `time`, which is not reliable at all, but using
`(trace last-pair)` shows accurately what happens with the iterations.
