[LayoutNG] Discard cache hit result if marked for layout.
(continued from (abandoned) CL:1719269)
During relayout, when we get a cache hit for a node, we still
recalculate overflow (why?). This may cause scrollbars to appear or
disappear, which will mark for layout. If this happens, we need to
discard the cached result and perform regular layout instead.
There *may* be legitimate reasons for adding or removing scrollbars on
a node that doesn't need relayout (although I cannot think of any), but
in this case (the test case), we gain a scrollbar because of some
amazing code in LayoutBlock::ComputeLayoutOverflow(), which adds 1px
hardcodedly, to the overflow rectangle width.
