This bug was causing it to be impossible to single-step to locations which had deleted breakpoints. In fixing this problem, another issue was exposed, where, if we single step while at a breakpoint, we would hit the same pc twice in the debugger. I have added a "skip step" mechanism which allows us to skip the next single-step after a breakpoint. Added a test.
