The Float16Array proposal for JavaScript adds a new TypedArray type holding IEEE binary16 floats. This PR adds it to all of the lists of TypedArray types in WebIDL.

Implementations of the proposal are underway in at least Chrome and Firefox, though it'll be some time before they're shippable. I don't know what the appropriate time to merge this is but I figured I should at least open it.

This is a JS feature, but adding it to ArrayBufferView has implications for any API which takes a generic TypedArray, which is quite a few of them. Does that imply they all need new tests? Hopefully not?

Fixes #1310.

(See WHATWG Working Mode: Changes for more details.)

Looks good, thanks! I think it would be good to also add web-platform-tests coverage. We have a couple tests that check if each of the typed arrays are supported by postMessage(), fetch(), and the like and it would be good to add Float16Array there. A grep for one of the rarer types will likely return those tests.

OK, opened a PR with tests.

Thanks @bakkot, I think the one thing remaining is that we should probably link the proposal if we are to merge this. Similar to how HTML has "[JSIMPORTATTRIBUTES]" and such. With that nit addressed I'd be willing to merge this Friday, barring any other feedback.

I stuck a link to the proposal in the table which defines the types, but I'm not sure that's the best way to do it. Happy to take suggestions for alternative ways to include the link.

I think the placement is good, but you want to use something akin to https://github.com/whatwg/fetch/blob/4c3750d3277e3df5ad452f48314eb29ca43b6461/fetch.bs#L58-L115 to add an official looking reference which you'd then reference from there.

Neat, done.

Added to Web IDL in whatwg/webidl#1398 and already used
in the definition of `ArrayBufferView`.

The test is not fantastically useful but will allow to make the test fail next
time we need to add a basic type to the list.
