Add an `fn_ptr` field to `MiriFrame` The `backtrace-rs` crate can use this to implement `Frame::symbol_address`, which is used to skip frames above the call to `Backtrace::capture` on the stack. The function pointer will not be useable for comparison purposes if the function is generic, as CTFE creates a new function pointer for each cast of a (monomorphized) generic function. However, this already affects code running under Miri, and isn't a problem for `backtrace-rs` (which only casts a non-generic function). I've added logic to allow `MiriFrame` to have either 4 or 5 fields - if a 5th field is present, we write the function pointer to it. 2020-10-10 12:07:57 -05:00			`$DIR/backtrace-api.rs:13:59 (func_d)`
