  [JSC] Ignore top byte in Integrity sanity checking on ARM64
https://bugs.webkit.org/show_bug.cgi?id=281187
rdar://137641787

Reviewed by Keith Miller.

Masks off top byte on ARM64 in Integrity::isSanePointer, since these bits
are ignored architecturally, and we don't want to fail pointer audits
if we use these bits for other things.
