summary:
bpo-44878: Remove the switch from the main interpreter loop when using computed gotos. (GH-27726)
* Refactor dispatch logic to make flow of control clearer. Moves lltrace and dxprofile instrumentation into DISPATCH macro.
* Remove switch in interpreter loop when using computed gotos. There is no need for two nearly-duplicate dispatch tables.
