Looks like you included the entirety of #81746 in this PR too. Edit: Didn't see #81746 (comment) yet. I would prefer making a new PR as the sync should be fine as is, but the rest will need to be reviewed independently. |

Sync `rustc_codegen_cranelift` Retrying rust-lang#84746 r? `@bjorn3` --- Edit(bjorn3): Since the last sync there have been some refactorings around the driver code in preparation for a planned new feature. In addition `@mominul` implemented `-Ctarget-cpu` support and `@XAMPPRocky` fixed compilation of cg_clif itself for Windows with the MSVC toolchain.
