Added a parse_amd() for CPU identification.

* This parses the reported CPU name, and tries to translate it to a normal
  and concise identifier.
* For example, it will translate "AMD FX(tm)-8320 Eight-core Processor" into
  "FX™ 8320" or "Dual Core AMD Opteron(tm) Processor 275 HE" into
  "Opteron™ 275 HE".
* This means we can remove AMD strings for those models for which this
  function produces useful results.
