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

Reviewed by Ryosuke Niwa.
MarkableTraits<WebCore::LayoutUnit>::emptyValue() was returning
LayoutUnit(-1), which is actually quite a valid value corresponding to
-1/64 pixels.
Instead it now uses a less common value, the same as
HashTraits<WebCore::LayoutUnit>::emptyValue() (which is justified in the
comment above.)
