beam_reorder: Don't confuse beam_validator
Make sure we don't optimize code such as: is_tuple Fail Src test_arity Fail Src Arity get_tuple_element Src Pos Dst is_map Fail Src If we would reorder the instructions like this: is_tuple Fail Src test_arity Fail Src Arity is_map Fail Src get_tuple_element Src Pos Dst beam_validator would complain that the type for Src is a map instead of a tuple. Since the code has problems to begin with, there is no need to do the optimization.
