Fixup test outside tests/asm.js.
This version also removes ArrayBuffer.transfer: if it's not removed, then there is a significant risk that lingering code compiled with "-s ALLOW_MEMORY_GROWTH=1" will use ArrayBuffer.transfer (only on Nightly) which, with neutering-support removed, would throw. There doesn't appear to be any movement on transfer in TC39 and no intention to implement in other engines, so this seems like the right thing to do at this time. It's easy enough to resurrect later.
