* Late Lint pass, catches: * One liner: 0 -> null -> transmute * One liner: std:null() -> transmute * Const (which resolves to null) -> transmute * UI Test case for Lint * Updated test for issue 3849, because now the lint that code generated is in Clippy. * Expanded `const.rs` miri-based Constant Folding code, to cover raw pointers
