68967252 - Support nice logging for `ProgramPoint*` in dataflow log (#154839)

Support nice logging for `ProgramPoint*` in dataflow log (#154839) There're places where a pointer instead of `ProgramPoint` object is passed to stream print `<<`, and they'll be printed as pointer value. This PR converts them to object before passing to stream printers. The address isn't much helpful in the debug and does not help when diffing before/after debug traces.
