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.
