(bpstat_what, bptype_string, print_one_breakpoint_location) (init_bp_location): Support bp_longjmp_call_dummy. (set_longjmp_breakpoint): Use longjmp_breakpoint_ops. Comment why. (set_longjmp_breakpoint_for_call_dummy) (check_longjmp_breakpoint_for_call_dummy, longjmp_bkpt_dtor): New functions. (initialize_breakpoint_ops): Initialize longjmp_breakpoint_ops. * breakpoint.h (enum bptype): New item bp_longjmp_call_dummy. Delete FIXME comment and extend the other comment for bp_call_dummy.
