-----------
Remove double negative from ArithClz32 backwards propagation
https://bugs.webkit.org/show_bug.cgi?id=266505
rdar://119694893
Reviewed by Justin Michaud.
Removes the extra ~ in front of NodeBytecodePrefersArrayIndex when
processing a DFG ArithClz32 node in the backwards propagation phase.
This makes it consistent with the other fields in the mask, instead
of the current behavior, which always masks off all other bits except
NodeBytecodePrefersArrayIndex.
