WhichRangesContainer, reduce malloc in SfxItemSet
SfxItemSet shows up in perf profiles frequently,
and the hottest part is the malloc of the two arrays we need.
But most of the time, one of those arrays is a compile-time
constant.
So this change introduces
(*) WhichRangesContainer, which manages whether the SfxItemSet
owns the array it points at or not.
(*) a static const member in svl::Items (idea from mkaganski)
to store the data.
