Yes, that is a standard "jit compile vs interpret" scenario.  LLVM should 
work well for that.

Just use standard calls to external functions, the JIT will autoresolve 
them to the current process.

You probably want to make one LLVM function per computation tree, the 
inputs to this would naturally become arguments to the function.
