description: >
  The `length` parameter is converted to a value numeric index value.
info: |
  SharedArrayBuffer( length )

  1. If NewTarget is undefined, throw a TypeError exception.
  2. Let byteLength be ? ToIndex(length).
  3. Return ? AllocateSharedArrayBuffer(NewTarget, byteLength).

  ToIndex( value )

  1. If value is undefined, then
    a. Let index be 0.
  2. Else,
    a. Let integerIndex be ? ToInteger(value).
    b. If integerIndex < 0, throw a RangeError exception.
    c. Let index be ! ToLength(integerIndex).
    d. If SameValueZero(integerIndex, index) is false, throw a RangeError exception.
  3. Return index.
