Enable last value generation of periodic sequence.
Rationale:
This helps to eliminate more dead induction. For example,
CaffeineLogic when compiled with latest Jack improves with
a 1.3 speedup (2900us -> 2200us) due to eliminating first
loop (second loop can be removed also, but for a later
case). The currently benchmarks.dex has a different construct
for the periodics, however, still to be recognized.
Test: test-art-host
