    Rename cast_op::type to type_name
    
    The existing name shadowed expression::type, and we can't have that...

    The Death of target_symbol::base_name
    
    Once upon a time, target_symbol was not a symbol, such shame.
    But lo! one fateful day, an new inheritance raised its game.
    Henceforth let target_symbol be known by its symbol::name.

    PR3672: Auto-stringify char* and char[]
    
    * tapsets.cxx (dwarf_pretty_print::print_chars): New, if the referenced
      type looks like a C-string, dereference it as such.
      (dwarf_pretty_print::recurse_array): Try print_chars first.
      (dwarf_pretty_print::recurse_pointer): Ditto.
    * tapset/conversions.stp (kernel_string2): New, with error string.

    PR3672: don't print "_vptr.foo" members
    
    The only use I can think for the vtable pointer is to try to identify an
    instance's subclass, but I don't think that's useful in the general
    case.  We might want to think about how to expose that for power users
    though, because our syntax doesn't allow "$p->_vptr.foo".
    
    * tapsets.cxx (dwarf_pretty_print::recurse_struct_members): Filter out
      members which start with "_vptr.foo".

    Ensure synthetic functions get symbol resolution
    
    When writing the pretty-print functions, I had trouble because the
    referents weren't being automatically filled in.  Rather than assigning
    them manually, this change now adds synthetic functions to the session
    in a way that they will get symbol resolution later.
    
    * elaborate.cxx (semantic_pass_symbols): Process probes before
      functions, in case synthetic functions are added to the file.
    * staptree.cxx (functiondecl::join): New, add a synthetic function to
      the session functions, and append it to the file's functions for later
      symbol resolution.
    * tapsets.cxx (dwarf_pretty_print::expand): Use fdecl->join to add the
      function to the session, and leave referents as default for later.
      (dwarf_pretty_print::deref): Ditto.
      (dwarf_var_expanding_visitor::visit_target_symbol): Ditto.
      (dwarf_cast_query::handle_query_module): Ditto.
      (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Ditto.
      (tracepoint_var_expanding_visitor::visit_target_symbol_context): Ditto.
    * tapset-procfs.cxx (procfs_var_expanding_visitor::visit_target_symbol):
      Ditto.
