    Original Commit Message:
    
        This introduces masking of loads with speculation bit during code generation.
        At the moment, this is done only under the
        --branch-load-poisoning flag, and this CL enlarges the set of supported
        platforms from {x64} to {x64, arm}.
    
        Overview of changes:
        - new register configuration configuration with one register reserved for
          the speculation poison/mask (kSpeculationPoisonRegister).
        - in codegen, we introduce an update to the poison register at the starts
          of all successors of branches (and deopts) that are marked as safety
          branches (deopts).
        - in memory optimizer, we lower all field and element loads to PoisonedLoads.
        - poisoned loads are then masked in codegen with the poison register.
          * only integer loads are masked at the moment.
