FIXME/cagney/2001-01-18: The logic is backwards. It should be asking if the
target can single step. If not, then implement single step using breakpoints.
- A return value of 1 means that the software_single_step breakpoints
- were inserted; 0 means they were not. Multiple breakpoints may be
- inserted for some instructions such as conditional branch. However,
- each implementation must always evaluate the condition and only put
- the breakpoint at the branch destination if the condition is true, so
- that we ensure forward progress when stepping past a conditional
- branch to self. */
