Disallow resizable ArrayBuffers for: - asm.js because it's not designed for resizable buffers. - DOM bindings because `mozilla::dom::TypedArray` caches the TypedArrays's length. - Structured cloning because I haven't yet checked how structured cloning should work when resizable ArrayBuffers are used.
