Fix new ArrayBuffer(length) for variaous input (#1959)

Currently new ArrayBuffer(length) does not conform to ES2017.
Major JS implementations follow ES2017 for ArrayBuffer(length).

For example, new ArrayBuffer(length) should not throw RangeError
for length = NaN, undefined, negative number, floating point, and so on.
