LOG: [SystemZ] Add serialization strings for some MO target flags. (#203053)

These strings are needed for MIR textual representation: If one is
missing it doesn't work to do "-stop-before=XXX and then
-start-before=XXX".

Added: 
    llvm/test/CodeGen/SystemZ/target-flags.ll

Modified: 
    llvm/lib/Target/SystemZ/SystemZInstrInfo.cpp

Removed:
