IE11 imul polyfill #42

Does this work on IE? It appears still to validate as asm.js in js24.

Thank. I can't check until tomorrow.

It works in IE11.

But I think Firefox slowed down. Without the polyfill, it seems to take about 0.5 seconds from "lbForth" to "ok". With the polyfill, more like 1 second.

Similar with Chrome.

Or maybe not! I tried reloading many times. I do see some apparent slowdown sometimes, but it seems to go away when I reload the page again. So maybe it's just due to some cache being warmed up.

I measured with console.time() and console.timeEnd(), and things seem good.
