[JSC] Implement Float16Array
https://bugs.webkit.org/show_bug.cgi?id=257022
rdar://109883982

Reviewed by Yijia Huang.

This patch adds Float16Array implementation. In the subsequent patch, we will implement JIT optimization in ARM64 for Float16Array too.
Basically, it is just a TypedArray with Float16. wtf/Float16.h implements Float16 data structure, and we just use it to implement Float16Array in JSC.

FYI there's a utility Array.isTypedArray defined in Source/WebInspectorUI/UserInterface/Base/Utilities.js that could use updating like this as well :)

[JSC] Implement Float16Array

Reviewed by Yijia Huang.

This patch adds Float16Array implementation. In the subsequent patch, we will implement JIT optimization in ARM64 for Float16Array too.
Basically, it is just a TypedArray with Float16. wtf/Float16.h implements Float16 data structure, and we just use it to implement Float16Array in JSC.
