[JSC][Wasm] Use ARM64 post-index in the restore-frame copy
https://bugs.webkit.org/show_bug.cgi?id=323374
Reviewed by Yusuke Suzuki.
The wasm-to-wasm restore-frame copy loop does loadPair64, storePair64
at base minus restoreFrameSize, then addPtr 16. ARM64 already has
loadPair64(PostIndexAddress). Fold the increment into the load and
store at the adjusted negative offset. Other architectures keep the
add.
