    PR11785: Fix pretty-printing for tracepoint base types
    
    We need slightly special code to deal with tracepoint base types, which
    should not be dereferenced at all, but just used as-is.
    
    * tapsets.cxx (dwarf_pretty_print): Add deref_p, which is usually true,
      but is false for tracepoints if "pointer" is really a direct value.
      (dwarf_pretty_print::deref): Copy the value directly if !deref_p.
      (dwarf_pretty_print::recurse_pointer): Detect void pointees more
      reliably, e.g. in case of a const node with no type -> const void.
      (dwarf_cast_query::handle_query_module): @cast always has deref_p.
      (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Permit
      pretty-printing on !isptr args, and use that to set deref_p.
      (tracepoint_derived_probe::resolve_tracepoint_arg_type): Check
      pointers more carefully for a pointee type, again for const void.

    Include session::compatible in the script hash
    
    Now that the compatibility version has runtime-level effects, we need to
    include it in the script hash.
    
    * hash.cxx (find_script_hash): Add session::compatible.
