Allow casting mut array ref to mut ptr We now allow two new casts: - mut array reference to mut ptr. Example: let mut x: [usize; 2] = [0, 0]; let p = &mut x as mut usize; We allow casting const array references to const pointers so not allowing mut references to mut pointers was inconsistent. - mut array reference to const ptr. Example: let mut x: [usize; 2] = [0, 0]; let p = &mut x as const usize; This was similarly inconsistent as we allow casting mut references to const pointers. Existing test 'vector-cast-weirdness' updated to test both cases. Fixes #24151 2021-01-28 11:22:33 -06:00			error[E0606]: casting `&[u8; 2]` as `*mut u8` is invalid
