[JSC] Refine JSObject::crashDueToEmptyValueAtValidOffset data
https://bugs.webkit.org/show_bug.cgi?id=324194
rdar://187412221
Reviewed by Mark Lam.
This patch replaces some of the debug data in
JSObject::crashDueToEmptyValueAtValidOffset with new data about
the structure's dictionary status. This will help refine the
hypothesis derived from previous data. The top nibble of the
crash reason (previously 0x900d0ff5e7bad) has been incremented
to help distinguish between revisions of the reported data.
No new tests because we don't have a repro to trigger the crash.
