Interface of a Rust codegen backend

This crate defines all the traits that have to be implemented by a codegen backend in order to use the backend-agnostic codegen code in rustc_codegen_ssa.

The interface is designed around two backend-specific data structures, the codegen context and the builder. The codegen context is supposed to be read-only after its creation and during the actual codegen, while the builder stores the information about the function during codegen and is used to produce the instructions of the backend IR.

Finally, a third Backend structure has to implement methods related to how codegen information is passed to the backend, especially for asynchronous compilation.

The traits contain associated types that are backend-specific, such as the backend’s value or basic blocks.
