[WIP] Herbert/use side channel for state changes

[HerbertJordan]

The idea of this PR is to remove the hardly modified state from the data that is propagated copied and checked in the interpreter loop. Instead, the program pointer (pc) is used to signal termination.

On Clang: 14.0.0, based on #161
