[JSC] Use runtime indexing type for write barrier in
operationPopulateObjectInOSR
https://bugs.webkit.org/show_bug.cgi?id=313170
rdar://175456941
Reviewed by Keith Miller.
operationPopulateObjectInOSR was checking materialization->indexingType()
(the compile-time type) to decide whether to issue a write barrier after
populating a PhantomNewArrayWithButterfly. The correct check is against
the array's actual runtime indexing type.
