Quartus-II synthesis/compile errors for Arria V device

Note that the patch is to add to 13.0sp1 only.

In addition to this problem I now discovered another synthesis problem in Quartus-II with nested case statement. However I have not been able to create a reduced-size test case for it. When the size is reduced the problem goes away. What I did to my design is to replace all the nested case statements with if/else statements. So far I can work around this later problem.
