kill is not OA_DANGEROUS
OA_DANGEROUS indicates that temporary copies may need to be made in
list assignment, to handle things like:
($a, $b) = ($b, $a);
In other words, an op type is flagged with OA_DANGEROUS if its return
values could occur elsewhere on the stack.
kill only ever returns a target unused elsewhere, so it does not
necessitate temp copies in list assignment.
