libjit/attic

As part of Google's Summer of Code, I am porting libjit to the alpha 
architecture for the GNU Project. Please be aware that this is still 
very much a work in progress and isn't functional yet. You can follow my 
progress via my blog: http://mediumbagel.org/nucleus/index.php?catid=6

For the first iteration, the alpha port will not implement floating-
point arithmetic. This is done to reduce complexity and to get libjit
working on alpha sooner. Advanced features like prefetching, hints (for 
jmp, jsr, ret, and jsrco), and branch elimination with cmov are 
optimizations that will be implmented once the alpha port is functional.
