Emacs Lisp JIT Compiler

Hi. I've written a JIT compiler for Emacs Lisp, and I'd like to check it in. This JIT is based on GNU libjit, like some other attempts that have come before it. However, this one is somewhat faster than those, primarily because it does all stack manipulations at compile time, not runtime. In some simple benchmarks, it is about 3x faster than the bytecode interpreter. I have only tested this on x86
