Recommend having both MAP_ADD and STORE_MAP.  The latter is repeated
often in a typical dict literal so it needs to be compact and fast.  The
former needs the flexibility of the offset argument to be workable in a
dict comprehension.  I also like that MAP_ADD eliminates the need for
the awkward ROT_TWO stack re-arrangement.  Also, MAP_ADD can include a
PREDICT(JUMP_ABSOLUTE) for a further speed-up.  All in all, this is a
nice clean-up and speed-up that more than justifies a second opcode.
