(dwarf_var_expanding_copy_visitor::visit_target_symbol): Optimization. Instead of generating one entry probe per target variable accessed in a return probe, now just generates one entry probe for all target variables accessed in a particular return probe. It does this by creating a new probe in the new 'add_probe' member variable. (dwarf_derived_probe::dwarf_derived_probe): If add_probe isn't NULL, make sure it gets derived later.
