RFR(S): 8211145: [ppc] [s390]: Build fails due to -Werror=switch (introduced with JDK-8211029)

[Schmidt, Lutz]

Hi Aleksey & All, 

I have changed the "sneaky" code such that it now looks more "enterprise grade". Please find an updated webrev at
Webrev: http://cr.openjdk.java.net/~lucy/webrevs/8211145.01/ 
Bug:    https://bugs.openjdk.java.net/browse/JDK-8211145 

Thanks,
Lutz

        Sneaky. Dear God. Can we please use the new enum constant in those case labels then? This would be a
        fun source of bugs otherwise if "bcondNotHigh  + bcondNotOrdered" carries over some bits :)
    
    Sure. I will provide a new webrev first thing Thursday morning. Need to rush out now...
    Thanks,
