Rollup merge of #104110 - krasimirgg:msan-16, r=nagisa 
prevent uninitialized access in black_box for zero-sized-types

Don't read the pointer location in black_box for zero sized types, just emit a memory clobber instead. Addresses  https://github.com/rust-lang/rust/issues/103304 when rust is build against LLVM at HEAD.

README.md

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.
