Log Message:
-----------
[JSC][Wasm] ESM mutable globals should be live unwrapped bindings
https://bugs.webkit.org/show_bug.cgi?id=322116
Reviewed by Yusuke Suzuki.
Namespace get of a mutable Wasm global returns the current value
instead of the WebAssembly.Global wrapper. Instance.exports stays
wrapped. v128 / exnref stay TDZ. Module-namespace IC is not installed
for these gets so the value stays live. A JS module that exports a
mutable WebAssembly.Global is unchanged.
