Implemented according to:
- AP-485 Intel(C) Processor Identification and the CPUID Instruction http://www.intel.com/design/xeon/applnots/241618.htm
- Intel(R) 64 and IA-32 Architectures Software Developer's Manual, Volume 2A: Instruction Set Reference, A-M http://developer.intel.com/design/pentium4/manuals/index_new.htm
- AMD CPUID Specification Publication # 25481 http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25481.pdf
Example:

    import std.cpuid;
    import std.stdio;

    void main()
    {
        writefln(std.cpuid.toString());
    }
