* Cranelift: Remove `ABICallee` trait It has only one implementation: the `ABICalleeImpl` struct. By using that directly we can avoid unnecessary layers of generics and abstractions as well as a couple `Box`es that were previously putting the single implementation into a `Box<dyn>`. * Cranelift: Rename `ABICalleeImpl` to `AbiCallee` * Fix comments as per review * Rename `AbiCallee` to `Callee`
This crate contains the core Cranelift code generator. It translates code from an intermediate representation into executable machine code.
