Implemented threading for x86_64.

Browse Source 
* Thread creation and switching is working fine, however threads do not yet
  get interrupted because I've not implemented hardware interrupt handling
  yet (I'll do that next).
* I've made some changes to struct iframe: I've removed the e/r prefixes
  from the member names for both 32/64, so now they're just named ip, ax,
  bp, etc. This makes it easier to write code that works with both 32/64
  without having to deal with different iframe member names.
