    Original Commit Message:
    
        ... so that the offset fits into the maximum offset for load byte
        instruction for arm/arm64 (Ldrb) in order to produce smaller code.
    
        Update code generation so that the loading of the flag value is
        combined with the comparison operation where possible.
    
        Additionally, this CL moves the Isolate::is_profiling flag to the
        IsolateData so that it can be loaded directly via roots register which
        removes one indirection.
    
        The fields moved in the IsolateData:
         - is_marking_flag and is_minor_marking_flag (checked by write barriers)
         - is_profiling (checked on API callbacks/getter calls)
         - stack_is_iterable (not super hot, checked during deoptimization).
    
        the field size expectations clear.
