PPC/s390: Reland: [TypeFeedbackVector] Store optimized code in the vector

Original Commit Message:

    Since the feedback vector is itself a native context structure, why
    not store optimized code for a function in there rather than in
    a map from native context to code? This allows us to get rid of
    the optimized code map in the SharedFunctionInfo, saving a pointer,
    and making lookup of any optimized code quicker.
