Created Revert of for-of should throw if result object is not an object
Description:
Revert of for-of should throw if result object is not an object (patchset #4
id:60001 of https://codereview.chromium.org/929733003/)
Reason for revert:
Broke compile
Original issue's description:
for-of should throw if result object is not an object
This is done using desugaring. Before this we had:
result = iterator.next()
with this we instead do:
!%_IsSpecObject(result = iterator.next()) &&
%ThrowIteratorResultNotAnObject(result)
