I have found a test which runs into the `ShouldNotReachHere()`: jdk/incubator/vector/VectorMaxConversionTests.java#ZGenerational I think we should revert all changes in `SaveLiveRegisters` (barrierSetAssembler_ppc.cpp) and `XSaveLiveRegisters` (xBarrierSetAssembler_ppc.cpp). We can keep them saving and restoring CR. Sorry for not finding this earlier.

No problem @TheRealMDoerr . Thanks for fix. I have reverted the changes and now the test jdk/incubator/vector/VectorMaxConversionTests.java is passing. I will run tier1 one more time
