Marco Zehe b96e455eb6 Bug 1503964 - Prevent crashes when dealing with crazy table row and column role constructs, r=Jamie
Made IsTableCell() only check the generic type, not the ARIA map entry that gets checked in HasGenericType. This prevents the crash and also fixes IsTableCell() and AsTableCell() not being in sync.
