document unrolled PUSHSUB/POPSUB

some places in the code do some or all of the same activities as
PUSHSUB() and POPSUB(). Add comments in those places pointing out that
it's a partially unrolled PUSH/POPSUB(). This will also help if someone
greps the code looking for all the places in core that supposedly does
a PUSH/POPSUB.
