description: Default [[Prototype]] value derived from realm of the NewTarget.
info: |
Intl.Segmenter ([ locales [ , options ]])
1. If NewTarget is undefined, throw a TypeError exception.
3. Let segmenter be ? OrdinaryCreateFromConstructor(NewTarget, "%Segmenter.prototype%", internalSlotsList).
...
15. Return segmenter.
OrdinaryCreateFromConstructor ( constructor, intrinsicDefaultProto [ , internalSlotsList ] )
...
2. Let proto be ? GetPrototypeFromConstructor(constructor, intrinsicDefaultProto).
3. Return ObjectCreate(proto, internalSlotsList).
GetPrototypeFromConstructor ( constructor, intrinsicDefaultProto )
...
3. Let proto be ? Get(constructor, 'prototype').
4. If Type(proto) is not Object, then
a. Let realm be ? GetFunctionRealm(constructor).
b. Set proto to realm's intrinsic object named intrinsicDefaultProto.
5. Return proto.
