[JSC] Disable BIGINT32 optimization temporarily because of SP2 / JS2 regression
https://bugs.webkit.org/show_bug.cgi?id=214776
Reviewed by Darin Adler.
We disable BIGINT32 optimization because it causes 1% regression in JetStream2 and Speedometer2.
We should enable it after we fix the cause of regression.
