Typeck: Disallow scalar casts to bare_fn.
Bare functions are another example of a scalar but non-numeric type (like char) that should be handled separately in casts. This disallows expressions like `0 as extern "Rust" fn() -> int;`. It might be advantageous to allow casts between bare functions and raw pointers in unsafe code in the future, to pass function pointers between Rust and C. Closes #8728
