Third time's the charm. Fix for https://github.com/llvm/llvm-project/pull/78482.
I did not understand how RegClassOrRegBank works compared to const TargetRegisterClass *. Pointers to RegClassOrRegBank  can't be used since actual object RegClassOrRegBank can me moved when data structure, where RegClassOrRegBanks are stored, in MachineRegisterInfo in needs to increase its size. Change is to use RegClassOrRegBank instead of pointer to RegClassOrRegBank, they also have same size.
