Rebased and removed the `Uint8ClampedArray` from this MR, I will send that on next MR with a couple more fixes now.

I'd suggest passing the descriptor as a struct pointer (moving resolving `typed_array_descs` to the caller) where possible.

`arrType` is a constructor not an array type, please name it like that.

`arr` is used for array instances in the same function, which makes things confusing.

This is already tested in documentmode.js.

Something like `test_own_data_prop_desc(constr.prototype, ....);` would make it easier to see what you're testing.

It doesn't seem all that useful, you could just check for `class == JSCLASS_DATAVIEW || (check *_TYPEDARRAY_JSCLASS)`.
