This broke this test when run in the JS shell.  See three lines up where AsmJSArrayBuffer could be used here?  That function (in the sibling shell.js file) depends on its |this| being the global object.  Fixed now:

Unfortunately, this test is skipped when not run in the JS shell, so this didn't show up on Tinderbox.  :-(
Thanks for catching that!
