    Update all the Intel JSON metrics from Ahmad Yasin's TMAM 3.5
    for Intel big core from Sandy Bridge to Cascade Lake.
    
    This has many improvements and new metircs
    
    - New TopDownL1_SMT group that provides a per SMT thread version
    of --topdown that does not require -a anymore. The drawback is
    increased multiplexing though since L1 TopDown does not fit into
    4 generic counters anymore.
    
    - Added SMT aware versions of other metrics
    
    - Split SMT aware metrics into separate metrics to avoid
    unnecessary event collections
    
    - New metrics for better branch analysis:
    Estimated Branch_Mispredict_Costs, Instructions per taken Branch,
    Branch Instructions per Taken Branch, etc.
    
    - Instruction mix metrics:
    Instructions per load, Instructions per store, Instructions per Branch,
    Instructions per Call
    
    - New Cache metrics:
    Bandwidth to L1/L2/L3 caches. L1/L2/L3 misses per kilo instructions.
    memory level parallelism
    
    - New memory controller metrics:
    Normalized memory bandwidth in interval mode, Average memory latency,
    Average number of parallel read requests,
    
    - 3DXP persistent memory metrics for Cascade Lake:
    3dxp read latency, 3dxp read/write bandwidth
    
    - Some other useful metrics like Instruction Level Parallelism,
    
    - Various other improvements.
    
    Not all metrics are available on all CPUs. Skylake has best coverage.
