The Great Generics Generalisation: HIR Followup
Addresses the final comments in #48149.
r? @eddyb, but there are a few things I have yet to clean up. Making the PR now to more easily see when things break.

Now that the `Buf` vs. non-`Buf` distinction has been removed, it makes
sense to drop the `Buf` suffix and use the shorter names everywhere.

Cleanup to librustc::session and related code
No functional changes, just some cleanup.
This also creates the `rustc_fs_util` crate, but I can remove that change if desired. It felt a little odd to force crates to depend on librustc for some fs utilities; and also seemed good to generally keep the size of librustc lower (for compile times); fs_util will compile in parallel with essentially the first crate since it has no dependencies beyond std.

cleanup: Remove `Def::GlobalAsm`
Global asm is not something that needs to have a `Def` or `DefId`.

This is a clippy-breaking change.

Don't format!() string literals
Prefer `to_string()` to `format!()` take 2, this time targetting string literals. In some cases (`&format!("...")` -> `"..."`) also removes allocations. Occurences of `format!("")` are changed to `String::new()`.

Prefer to_string() to format!()
Simple benchmarks suggest in some cases it can be faster by even 37%:
```
test converting_f64_long ... bench: 339 ns/iter (+/- 199)
test converting_f64_short ... bench: 136 ns/iter (+/- 34)
test converting_i32_long ... bench: 87 ns/iter (+/- 16)
test converting_i32_short ... bench: 87 ns/iter (+/- 49)
test converting_str ... bench: 54 ns/iter (+/- 15)
test formatting_f64_long ... bench: 349 ns/iter (+/- 176)
test formatting_f64_short ... bench: 145 ns/iter (+/- 14)
test formatting_i32_long ... bench: 98 ns/iter (+/- 14)
test formatting_i32_short ... bench: 93 ns/iter (+/- 15)
test formatting_str ... bench: 86 ns/iter (+/- 23)

rustc_metadata: test loading atoi instead of cos
Some platforms don't actually have `libm` already linked in the test
infrastructure, and then `dynamic_lib::tests::test_loading_cosine` would
fail to find the "cos" symbol. Every platform running this test should
have `libc` and "atoi" though, so try to use that symbol instead.
Fixes #45410.

Rollup of bare_trait_objects PRs
All deny attributes were moved into bootstrap so they can be disabled with a line of config.
Warnings for external tools are allowed and it's up to the tool's maintainer to keep it warnings free.

rustc: Register crates under their real names
Whenever we register a crate into the crate store, make sure to use the real
name mentioned in the metadata instead of the name mentioned in the `extern
crate` statement, as the statement can be wrong!
Closes #51796

Prepare proc_macro for decoupling it from the rest of the compiler.
This is #49219 up to the point where the bridge is introduced. Aside from moving some code around, the largest change is the rewrite of `proc_macro::quote` to be simpler and do less introspection.
I'd like to also extend `quote!` with `${stmt;...;expr}` instead of just `$variable` (and maybe even `$(... $iter ...)*`), which seems pretty straight-forward now, but I don't know if/when I should.

rustc: Stabilize #[wasm_import_module] as #[link(...)]
This commit stabilizes the `#[wasm_import_module]` attribute as
`#[link(wasm_import_module = "...")]`. Tracked by #52090 this new directive in
the `#[link]` attribute is used to configured the module name that the imports
are listed with. The WebAssembly specification indicates two utf-8 names are
associated with all imported items, one for the module the item comes from and
one for the item itself. The item itself is configurable in Rust via its
identifier or `#[link_name = "..."]`, but the module name was previously not
configurable and defaulted to `"env"`. This commit ensures that this is also
configurable.
Closes #52090
