Both die_find_variable_by_reg and die_find_variable_by_addr call match_var_offset which already performs sufficient checking and type matching. The additional check_variable call is redundant, and its need_pointer logic is only a heuristic. Since DWARF encodes accurate type information, which match_var_offset verifies, skipping check_variable improves both coverage and accuracy. Return the matched type from die_find_variable_by_reg and die_find_variable_by_addr via the existing `type` field in find_var_data, removing the need for check_variable in find_data_type_die.
