There are four scenarios being handled in this function:
- single stepping
- hardware breakpoints
- software breakpoints
- fallback (no debug supported)
A future patch will add code to handle specific single step and
software breakpoints cases so let's split each scenario into its own
function now to avoid hurting readability.
