Subject: [PATCH] Editorial: Remove unnecessary checks for undefined before
 ToPositiveInteger

`ToPositiveInteger(undefined)` calls
`ToIntegerThrowOnInfinity(undefined)`, which in turn calls
`ToIntegerOrInfinity(undefined)`, which in turn calls
`ToNumber(undefined)`. `ToNumber` returns `NaN`, `ToIntegerOrInfinity`
then returns `0`, `ToIntegerThrowOnInfinity` returns `0` unchanged, and
finally `ToPositiveInteger` will throw a RangeError for `0`. That means
it's not necessary to handle `undefined` before calling
`ToPositiveInteger`.
