Remove OA_DANGEROUS from cond_expr

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.

?: always returns one of its arguments.  Since aassign_common_vars,
which does the danger check, also checks the kids of the cond_expr op,
it is not necessary for cond_expr to be flagged this way.
