commit 5f36109ef05d8399e6369c0487a0a17d40ad3267

    PR3672: Add pretty-printing for compound types
    
    This adds a new syntax for pretty-printing variables as strings:
    
      $var$         $var$$         $var->$            $var->$$
      $@cast(...)$  $@cast(...)$$  $@cast(...)->$     $@cast(...)->$$
      $var->foo->$  $var[1]->$     $@cast(...)->foo$  $@cast(...)[2]$
    
    This is still a work in progress, but I deemed it now useful enough to
    share.  See PR3672 for discussion of work remaining.
    
    * parse.cxx (parser::parse_target_symbol_components): Parse the trailing
      $s as a new comp_pretty_print entry in the target_symbol.
    * staptree.cxx (target_symbol::assert_no_components): Add a flag to
      assert whether pretty-printing is supported.
      (target_symbol::component::print): Support comp_pretty_print.
    * dwflpp.cxx (dwflpp::translate_components): Skip the actual translation
      if the obstack "pool" is NULL.
      (dwflpp::type_die_for_local): Dig through a local and its components
      to get the type DIE that the pretty printing can start from.
      (dwflpp::type_die_for_return): Ditto for return values.
      (dwflpp::type_die_for_pointer): Ditto for pointers.
    * tapsets.cxx (dwarf_pretty_print): New struct for recursing over a type
      DIE and producing a string representation.  (The real meat lies here!)
      (dwarf_var_expanding_visitor::visit_target_symbol): Determine when to
      use dwarf_pretty_print instead of the normal path.
      (dwarf_var_expanding_visitor::visit_target_symbol_context): Ditto.
      (tracepoint_var_expanding_visitor::visit_target_symbol_arg): Ditto.
      (tracepoint_var_expanding_visitor::visit_target_symbol_context): Ditto.
      (dwarf_cast_query, dwarf_cast_expanding_visitor): Move the function
      generation from the visitor to the query, and also support using
      dwarf_pretty_print as needed.
