PIL -> rust compiler (#1416)

This is a (yet unused) component that takes an `Analyzed` and a list of
names and turns these names into `fn(u64) -> u64` to be called directly.

Not all syntax is supported yet (and no built-in functions).

The first goal is not be able to compile all constant functions.

The benchmarks show that `sqrt` is roughly 10 times faster than the
evaluator.
