The `DataView` constructor shouldn't be able to return a `DataView` instance
backed by a detached `ArrayBuffer` when `OrdinaryCreateFromConstructor`
returns an instance so backed.
info: |
`OrdinaryCreateFromConstructor` has the potential to invoke user-defined code
that may detach the `ArrayBuffer` intended to underlie the fresh instance.
Verify that a final is-detached check is performed before the new instance is
returned.

Provide a list for original and expected values for different byte

This helper is mostly used on tests for TypedArray and DataView, and each
array from the expected values must match the original values array on every
index containing its original value.
