[JSC] Wasm Table index must be extended when using 64bit Table
https://bugs.webkit.org/show_bug.cgi?id=321031
rdar://184064205
Reviewed by Cole Carley.
In Table64, index should be represented as i64. As a result, operation
are taking uint64_t, but we are not zero-extending the passed i32 index
appropriately. This patch fixes them.
