Python 3.9 introduced the JUMP_IF_NOT_EXC_MATCH opcode, and the use of Compare.EXC_MATCH produces bad code that results in

TypeError: 'UH��H��]�l�' not supported between instances of 'type' and 'type'

therefore I would like to suggest that the attribute Compare.EXC_MATCH be defined only under the condition sys.version_info[:2] < (3, 9)

Sounds perfectly reasonable. Please make a PR.
