Description: This is the second part of the implementation of bpo-39320. Part 1 was #17984 This PR replaces BUILD_MAP_UNPACK and BUILD_MAP_UNPACK_WITH_CALL with DICT_MERGE and DICT_UPDATE. DICT_UPDATE n calls item_n.update(tos) where item_n is the nth item on the stack and tos is popped from the stack. DICT_MERGE n is the same, but raises an exception if there are duplicate keys. https://bugs.python.org/issue39320
