New submission from Demur Rumed <junkmute at hotmail.com>:
This modifies the peepholer's BUILD/UNPACK_SEQUENCE for the case when all stores are simple, or all loads are simple
It first scans to see if the pushing is done with simple LOADs. If so, it reverses the loads and removes the build unpack. If not, it scans ahead to see if it is followed by simple STOREs. If so, it reverses the stores and removes the build unpack
