HashMaps require that their keys not be 0

I think this will fail if there are 0 items in the array. I suggest you filter those out.

The enums I'm using as the keys here are never 0.

This line is only called if the array exists (hence, not empty).

after changes in https://trac.webkit.org/changeset/239495/webkit

we are seeing around 13 test failures on WK2 for Sierra. Most of these are webgpu/ tests.

Wenson said that this patch turned webgpu off for Sierra and thus these tests may need to be skipped now. Justin can you confirm this?

Perhaps I've missed something here, but I can't seem to find where WK_IOS_1100 is defined.
