It's not in the gdb script, it's in gdb proper.

If you care to have a peek, look at

  /* Handles single stepping of atomic sequences.  */
  set_gdbarch_software_single_step (gdbarch, ppc_deal_with_atomic_sequence);

in gdb/rs6000-tdep.c.  It ought to be fairly easy to write
something similar for alpha-tdep.c.
