Map.prototype.delete ( key )
4. Let entries be the List that is the value of M’s [[MapData]] internal slot.
5. Repeat for each Record {[[key]], [[value]]} p that is an element of entries,
a. If p.[[key]] is not empty and SameValueZero(p.[[key]], key) is true, then
i. Set p.[[key]] to empty.
ii. Set p.[[value]] to empty.
iii. Return true.
