3887 - clean up early exits in interpreter loop
It's always confusing when `break` refers to a `switch` but `continue` refers to the loop around the `switch`. But we've done ugly things like this and `goto` for expedience. However, we're starting to run into cases where we now need to insert code at every `continue` or `continue`-mimicking `goto` inside the core interpreter loop. Better to make the loop single-entry-single-exit. Common things to run after every instruction will now happen inside the `finish_instruction` function rather than at the `finish_instruction` label.
