mrambacher 55e99688cc No elide constructors (#7798) 
Summary:
Added "no-elide-constructors to the ASSERT_STATUS_CHECK builds.  This flag gives more errors/warnings for some of the Status checks where an inner class checks a Status and later returns it.  In this case,  without the elide check on, the returned status may not have been checked in the caller, thereby bypassing the checked code.
