-----------
Decompress the previous sibling and renderer pointers in WebCore::Node
https://bugs.webkit.org/show_bug.cgi?id=281997
rdar://138409833
Reviewed by Ryosuke Niwa.
Makes use of some currently unused padding bytes in WebCore::Node to
decompress two CompactPointerTuple fields, simplifying access to these
fields without increasing the memory footprint of Node itself.
