…esn't change. When the setter for the single-step flag is given an `enable` boolean that matches the existing state (i.e., enabling when already enabled or disabling when already disabled), we should not loop through and re-patch all breakpoint patch sites. This is an optimization, not required for correctness, but a rather obvious optimization to make (and important when building higher-level APIs for e.g. a single-step command that always set the flag).
