Reorder RenderTreeUpdater::Parent fields to eliminate struct padding
https://bugs.webkit.org/show_bug.cgi?id=319220

Reviewed by Chris Dumez.
previousChildRenderer (8-byte pointer) sat between two bools, forcing
alignment padding that inflated Parent to 72 bytes. Hoisting it above
both bools packs them adjacently, shrinking Parent to 64 bytes. Parent
is stored one-per-DOM-depth in m_parentStack. No behavior change.
