Summary: There is nothing we can do with the breakpoint once the associated target becomes deleted. This will make sure we don't hold on to more resources than we need in this case. In particular, this fixes the case TestStepOverBreakpoint on windows, where a lingering SBBreakpoint object causes us to nor unmap the executable file from memory.
