SIMD Polyfill

[thomasfoster96]

Obviously the performance benefits of SIMD can't be replicated in this library, but there is a fairly good polyfill available at ecmascript_simd.

I completely understand if this isn't worth doing, but this would save a lot of feature detection at the cost of performance when SIMD isn't available (it is in Firefox nightly only at the moment). A bit like how TypedArrays used to be polyfilled with plain old Arrays.

I think, it will be added in the future, but now we have some problems. It was already mentioned here.

• Typed arrays not available in old browsers, need add typed arrays polyfill before.
• It will add up to half of core-js size. Possible add it as optional feature.

~half? Wowsers. Sorry, I didn't see that in the README.

Optional feature sounds like a good idea. Making ES3 support (which I gather is the reason for no TypedArrays polyfill?) optional is another option.

SIMD was moved to inactive proposals list, so I'm closing it before the resumption of work on this proposal.
