Okay, let's see it.

I was mostly concerned with having the same control flow as before, did I miss some change that is
actually non-trivial? On the second read, this change in c1_LIRAssembler_aarch64.cpp looks
suspicious, as it elevates ShouldNotReachHere to default case, rather than letting default thing
fall-through?

         break;
+      default:
         ShouldNotReachHere();
       }
