Title: Fix array children in PHP5 and HHVM without EnableHipHopSyntax

Array isn't usually Traversable.

Fixes facebook/hhvm#2631

```
[fredemmott@devbig076 /tmp/xhp-bs] hhvm -v Eval.EnableXHP=1 -v
Eval.EnableHipHopSyntax=0 test.php
string(10) "foo"
string(10) "foo"
[fredemmott@devbig076 /tmp/xhp-bs] hhvm -v Eval.EnableXHP=1 -v
Eval.EnableHipHopSyntax=1 test.php
string(10) "foo"
string(10) "foo"
[fredemmott@devbig076 /tmp/xhp-bs] cat test.php
{['foo']});
var_dump((string) {new ArrayIterator(['foo'])});
```
