ArrayBuffer broken

[NathanaelA]

If you attempt to create a arraybuffer the runtime will crash.
Ex:
'''var ab =new ArrayBuffer (10);'''
I'm pretty sure it was crashing at creation; but since I'm on my phone

I can't verify right this sec. If that doesn't cause it to crash add
var ib = Int8Array(ab);
to the code and our will crash worth the error specifing an issue creating the arraybuffer.

The other direction also crashes the runtimes:
var ib = new Int8Array (10) ;
var ab = ib.buffer;

This is on v1.20 of the runtimes.
