This mostly looks good. I have a couple comments, but we'll have to wait for #122811 to merge first anyway.

I have updated and addressed the comments. I think this shouldn't land quite yet, to give a little more time for any fallout from #122810 to happen. I will be around on Monday but then I will be on vacation for three weeks. Maybe this should wait until I get back, just to be safe. |

r=me whenever you feel like we waited enough :) |

Replacing `mk_session` with `sess_and_cfgs`, which does a bit more of the shared stuff -- the option parsing and the `build_configuration` call.
Currently `SourceMap` is constructed slightly later than `SessionGlobals`, and inserted. This commit changes things so they are done at the same time. Benefits: - `SessionGlobals::source_map` changes from `Lock<Option<Lrc<SourceMap>>>` to `Option<Lrc<SourceMap>>`. It's still optional, but mutability isn't required because it's initialized at construction. - `set_source_map` is removed, simplifying `run_compiler`, which is good because that's a critical function and it's nice to make it simpler. This requires moving things around a bit, so the necessary inputs are available when `SessionGlobals` is created, in particular the `loader` and `hash_kind`, which are no longer computed by `build_session`. These inputs are captured by the new `SourceMapInputs` type, which is threaded through various places.
Currently it's a method on `EarlyDiagCtxt`, which is not the right place for it at all -- `EarlyDiagCtxt` is used to issue diagnostics, but shouldn't be doing any of the actual checking. This commit moves it into a standalone function that takes an `EarlyDiagCtxt` as an argument, which is more sensible. This does require adding `EarlyDiagCtxt::early_struct_warn`, so a warning can be returned and then modified with a note. (And that likely explains why somebody put `initialize_checked_jobserver` into `EarlyDiagCtxt` in the first place.)
