Fixes a bug where FIRST_VALUE may produce incorrect results (or a DCHECK failure in debug) when there is a window like "ROWS X PRECEDING Y PRECEDING", such that X < Y and X > the size of a partition. For windows with an end boundary that is PRECEDING (i.e. the entire window is before a row), there is some special handling between partitions, and the logic was not correct in some corner cases for FIRST_VALUE.
