-----------
Avoid CompactPtr expansion if unnecessary
https://bugs.webkit.org/show_bug.cgi?id=249572
rdar://103506006
Reviewed by Justin Michaud.
This patch adds operator== etc. for CompactPtr and adjust HashTraits for
CompactPtr so that
we can avoid pointer expansion while using CompactPtr in HashTable: comparison
of CompactPtrs
and hash computation don't need pointer expansion.
