Generate `operator<` bindings. For now operator<=> is completely ignored, and even if both operator< and operator<=> are present we construct partial_cmp from lt (i.e. the operator< thunk). Bindings are also not generated for operator< when the operands have different types, since that's a much more complicated case: implementing partial_cmp in Rust using lt would require transitivity of operator< and operator==, and we'd need to query salsa for them while avoiding cyclic queries.

Extremely experimental interop tooling for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
