For some data points, Eric started working on build system integration
(see below email). FFI will depend greatly on the component in question.
For a greenfield backend compiler that does NIR -> backed IR in C and
exposes the backend IR builders from Rust over a C ABI, there's little
in the way of FFI work needed to go. Conventions and style are easy --
go with rustfmt, the language is quite opinionated so we can quit
quibbling and get coding :)
