Here's a series of two, a bit more carefully done, patches. First
removes ExplainPropertyLong, expands ExplainPropertyInteger to
64bits. Second adds the unit argument.
Whether we want to go for the first one, or revise first patch to just
rename ExplainPropertyInt64 remains to be discussed. I still slightly
prefer the approach presented here.
