◆ MoveUpTranslationUnitIncludeHierarchy()

Given a decomposed source location, move it up the include/expansion stack to the parent source location within the same translation unit.

If this is possible, return the decomposed version of the parent in Loc and return false. If Loc is a top-level entry, return true and don't modify it.
