Fixes gh-696 As pointed in gh-696, the ArrayBuffer ctor won't throw a RangeError when invoked without arguments. Instead of fixing the invalid assertion, this commit removes it as the coverage for subclassing is already satisfied by the use of slice.

24.1.2 The ArrayBuffer Constructor
|
|
|
|
...
|
|
|
|
The ArrayBuffer constructor is designed to be subclassable. It may be used as
|
|
the value of an extends clause of a class definition. Subclass constructors
|
|
that intend to inherit the specified ArrayBuffer behaviour must include a
|
|
super call to the ArrayBuffer constructor to create and initialize subclass
|
|
instances with the internal state necessary to support the
|
|
ArrayBuffer.prototype built-in methods.
