Start of a new llvm-jit/ backend that assembles and executes x86 code in-process using LLVM MC + ORC, eventaully to replace the external clang/link/FFI pipeline. Includes a minimal C API, Makefile build, Racket FFI wrapper, and install-time build hook with LLVM validation.
Make the runtime symbol definitions belong to the same per-run ResourceTracker as the object file, so both get removed together after the run.
Currently the runtime.o files have main.o linked in, which is probably not the right design, but to keep things working with the langs code as is, this commit adds a set_global operation and uses it to mutate the existing globals in the runtime for things like in, out, heap, etc. At some point it would be better to remove main.o from runtime.o and just set these symbols.
This change sets up the error handler function correctly and also recovers gracefully from errors in executed code by starting up a new jit interpreter.

This replaces the command line and file based backend for implementing asm-interp with a new implementation that uses LLVM's library for constructing assembly code in memory and its JIT facilities for running that code. It is significantly faster and requires minimal changes to existing code.
