Thanks a bunch -- this will be really useful to have!

Should the second arg be a &MachineEnv? Alternately, no clone two lines below?
This PR has 2 components: - A `SerializableFunction` which wraps a `Function` and `MachineEnv`. This type can be serialized and deserialized with Serde, and is enabled by the "enable-serde" feature. - A `regalloc2-tool` binary which reads a bincode-encoded `SerializableFunction` and then runs the register allocator and checker on it. This is a useful tool for debugging register allocation failures and to investigate cases of poor register allocation.
