Reduce sizeof Line::Run by reordering members
https://bugs.webkit.org/show_bug.cgi?id=319565
rdar://182394518
Reviewed by Alan Baradlay.
Line::Run interleaved 8-byte-aligned members with 4-byte InlineLayoutUnits
and 1-byte enums, leaving three interior padding holes. Reorder by
descending alignment to pack them tightly, shrinking sizeof(Line::Run)
from 88 to 80 bytes.
Constructor initializer lists are reordered to match, keeping -Wreorder
clean. No behavior change.
