Rollup merge of #69922 - RalfJung:less-intrinsic, r=oli-obk 
implement zeroed and uninitialized with MaybeUninit

This is the second attempt of doing such a change (first PR: https://github.com/rust-lang/rust/pull/62150). The last change [got reverted](https://github.com/rust-lang/rust/pull/63343) because it [caused](https://github.com/rust-lang/rust/issues/62825) some [issues](https://github.com/rust-lang/rust/issues/52898#issuecomment-512182438) in [code that incorrectly used these functions](https://github.com/erlepereira/x11-rs/issues/99).

Since then, the [problematic code has been fixed](https://github.com/erlepereira/x11-rs/pull/101), and rustc [gained a lint](https://github.com/rust-lang/rust/pull/63346) that is able to detect many misuses of these functions statically and a [dynamic check that panics](https://github.com/rust-lang/rust/pull/66059) instead of causing UB for some incorrect uses.

Fixes https://github.com/rust-lang/rust/issues/62825

The codegen crate contains the code to convert from MIR into LLVM IR, and then from LLVM IR into machine code. In general it contains code that runs towards the end of the compilation process.

For more information about how codegen works, see the rustc dev guide.
