description: Return value according to [[ArrayBufferMaxByteLength]] internal slot
info: |
get SharedArrayBuffer.prototype.growable
1. Let O be the this value.
2. Perform ? RequireInternalSlot(O, [[ArrayBufferData]]).
3. If IsSharedArrayBuffer(O) is false, throw a TypeError exception.
4. Return IsResizableArrayBuffer(O).
IsResizableArrayBuffer ( arrayBuffer )
1. Assert: Type(arrayBuffer) is Object and arrayBuffer has an
[[ArrayBufferData]] internal slot.
2. If buffer has an [[ArrayBufferMaxByteLength]] internal slot, return true.
3. Return false.
