PPC/s390: [compiler] Teach InstructionScheduler about protected memory accesses

Port e301d71f

Original Commit Message:

    Because these instructions can trap, we don't want them to be reordered
    as freely as unprotected accesses.

    As part of this, make explicit which opcodes support a MemoryAccessMode.
