Rollup merge of #100037 - fw-immunant:patch-1, r=jyn514

Update rustc man page to match `rustc --help`

This brings the `--crate-type`,  `--emit`, and `--print` options' allowed arguments into sync with that printed by `rustc --help`.

c.f. the `opt::multi_s` calls for `"crate-type"`, `"emit"`, and `"print"` here: https://github.com/rust-lang/rust/blob/master/compiler/rustc_session/src/config.rs
