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

[Schmidt, Lutz]

Hi Aleksey,

you got me! I forgot to mention this one, sorry! With -Werror=switch, the compiler complains about line 131 in cpu/s390/assembler_s390.cpp:

       case bcondNotHigh  + bcondNotOrdered : inverse_cc = bcondHigh; break;                                                     // 13

The resulting case label was not declared in the enum Assembler::branch_condition.

Thanks, 
Lutz

    *) What is this change in assembler_s390.hpp? These new enum values are not used.
    
    1445     bcondLowOrNotOrdered  =  bcondLow  | bcondNotOrdered,  // float comparisons
    1446     bcondHighOrNotOrdered =  bcondHigh | bcondNotOrdered,  // float comparisons
    1447     bcondNotLowOrNotOrdered  =  bcondNotLow  | bcondNotOrdered,  // float comparisons
    1448     bcondNotHighOrNotOrdered =  bcondNotHigh | bcondNotOrdered,  // float comparisons
    
    *) Stylistically, it seems more consistent to break the line after "default" in some switches, for
    example here:
    
    3214     case Bytecodes::_fast_lputfield:
    3215       __ pop_l(Z_tos);
    3216       break;
    3217     default: break;
