[JSC] Fold WasmGC object comparisons
https://bugs.webkit.org/show_bug.cgi?id=318753
rdar://181552309
Reviewed by Keith Miller.
When Equal(@a, @b) are both WasmGC object allocations and @a != @b,
they must be different WasmGC cells, thus Equal(@a, @b) should be fold
into false. Same rule can be applied to NotEqual. Also when one side is
jsNull constant (ref.null), then it is also false when the other side is
WasmGC allocations.
