Merged x86_64 headers into x86 headers. Not many changes seeing as there's not much x86_64 stuff done yet. Small differences are handled with ifdefs, large differences (descriptors.h, struct iframe) have separate headers under arch/x86/32 and arch/x86/64.

Implemented threading for x86_64. * 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.
