Log Message:
-----------
[JSC] OpCallShape should include iterator_open and iterator_next

Reviewed by Alexey Shvayka.
We originally inserted this check since getter / setter opcodes (op_get_by_id
etc.) does not have ArrayProfile.
But now this also excludes iterator_open and iterator_next. This is wrong since
they have ArrayProfile correctly.
So we should list up them as OpCallShape, which allows emitting intrinsic-based
DFG nodes. For example,
for (var [key, value] of map);
needs this patch to emit Map#entries intrinsic.
