Begin fixing all the broken doctests in `compiler/` Begins to fix #95994. All of them pass now but 24 of them I've marked with `ignore HELP (<explanation>)` (asking for help) as I'm unsure how to get them to work / if we should leave them as they are. There are also a few that I marked `ignore` that could maybe be made to work but seem less important. Each `ignore` has a rough "reason" for ignoring after it parentheses, with - `(pseudo-rust)` meaning "mostly rust-like but contains foreign syntax" - `(illustrative)` a somewhat catchall for either a fragment of rust that doesn't stand on its own (like a lone type), or abbreviated rust with ellipses and undeclared types that would get too cluttered if made compile-worthy. - `(not-rust)` stuff that isn't rust but benefits from the syntax highlighting, like MIR. - `(internal)` uses `rustc_*` code which would be difficult to make work with the testing setup. Those reason notes are a bit inconsistently applied and messy though. If that's important I can go through them again and try a more principled approach. When I run `rg '```ignore \(' .` on the repo, there look to be lots of different conventions other people have used for this sort of thing. I could try unifying them all if that would be helpful. I'm not sure if there was a better existing way to do this but I wrote my own script to help me run all the doctests and wade through the output. If that would be useful to anyone else, I put it here: https://github.com/Elliot-Roberts/rust_doctest_fixing_tool |

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.
