dom/html: ArrayBuffer has no constructor

[rakudrama]

ArrayBuffer has no constructor.

The IDL has [CustomConstructor, ConstructorParameters=1].

A work-around is to use the buffer of a typed array:

  var buffer = new Int8Array(1000).buffer;

[rakudrama]

w3 IDL is: http://www.khronos.org/registry/typedarray/specs/latest/#­5

[ Constructor(unsigned long length) ]
interface ArrayBuffer {
    readonly attribute unsigned long byteLength;
    ArrayBuffer slice(long begin, optional long end);
};
