Summary MarkableTraits<WebCore::LayoutUnit>::emptyValue() should use a less common value

MarkableTraits<WebCore::LayoutUnit>::emptyValue() currently returns LayoutUnit(-1), which is actually quite a valid value corresponding to -1/64 pixels. Instead it should use a less common value, probably the same as HashTraits<WebCore::LayoutUnit>::emptyValue(), which is INT_MIN and justified as "During the course of layout // these values are typically only used to represent uninitialized values".
