If an alignment interrupt occurs on an instruction that is being single-stepped, the alignment interrupt handler currently handles the single-step condition by unconditionally sending a SIGTRAP to the process. Other synchronous interrupts that result in the instruction being emulated do likewise. With hw_breakpoint support, the hw_breakpoint code needs to be able to intercept these single-step events as well as those where the instruction executes normally and a trace interrupt happens. Fix this by making emulate_single_step() use the existing single_step_exception() function instead of calling _exception() directly. We then make single_step_exception() use the abstracted clear_single_step() rather than clearing bits in the MSR image directly so that emulate_single_step() will continue to work correctly on Book 3E processors.
