   If this is defined, then there must be a function declaration or inline
   for <code class="function">user_enable_block_step</code>, and <code class="function">arch_has_single_step</code> must be defined
   too.  <code class="function">arch_has_block_step</code> should evaluate to nonzero iff the machine
   supports step-until-branch for user mode.  It can be a constant or it
   can test a CPU feature bit.
