It would help issue47120 to reduce the number of jump opcodes.

The exception matching opcodes JUMP_IF_NOT_EXC_MATCH  and JUMP_IF_NOT_EG_MATCH are not hot, and we can split them into a check + ordinary jump. 

For JUMP_IF_NOT_EXC_MATCH  this is simple because the stack effect is the same for the jump and non-jump case. For JUMP_IF_NOT_EG_MATCH the stack effect will need to be made the same, and the opcodes emitted around it adapted.
