…r=WaffleLapkin interpret: refactor function call handling to be better-abstracted Add a new function `init_stack_frame` that pushes a stack frame and passes the arguments, and use that basically everywhere that the raw underlying `push_stack_frame` used to be called. This splits the previous monster function `eval_fn_call` into two parts: figuring out the MIR to call and the arguments to pass, and then actually setting up the stack frame. Also re-organize the files a bit: - The previous `terminator.rs` is split into a new `call.rs` with all the argument-passing logic, and the rest goes into `step.rs` where the other main dispatcher functions already live (in particular, `eval_statement`). - All the stack frame handling from `eval_context.rs` is moved to a new `stack.rs`.
