    Detect cache line size on Linux for PPC hosts. · c3ff68b6
    mbrandy authored
    In the interest of generalization, this change:
    - Consolidates cache line size detection for all interested
      architectures under base::CPU (currently leveraged by only
      PPC and ARM64).
    - Differentiates between instruction vs data cache line sizes.
