I think this was left out by accident from the "convert everything to
rlibs" commit, there's no need for this to be a dylib just as everything
else doesn't need to be a dylib!

Move `source_uitil` macros into `syntax_ext`
Cleanup dependencies of `rustc_driver`

Few other minor renamings for consistency.
Remove one unused dependency from `rustc_passes`.
Fix libsyntax tests.
Fix rebase.

`contents` is the whole file rather than a single line.

…me-elision-2, r=Centril

Allow lifetime elision in `Pin<&(mut) Self>`

This PR changes `self: &(mut) S` elision rules to instead visit the type of `self` and look for `&(mut) S` (where `is_self_ty(S)`) within it

Replaces rust-lang#60944

Closes rust-lang#52675

Break dependencies between `syntax_ext` and other crates

Move `source_util` macros into `syntax_ext`.
Move other early code generation facilities like standard library injection into `syntax_ext`.

The only crate that depends on `syntax_ext` now is `rustc_interface` which is one of the "final" crates that depend on everything.

Minor: Cleanup dependencies of `rustc_driver`, many of them are no longer used after introduction of `rustc_interface`.

rustc: Compile the `fmt_macros` crate as an rlib

tidy: Add a check for inline unit tests

As described in rust-lang#61097.

There's a large whitelist right now, because in many crates the tests are not outlined yet.
~This PR only outlines tests in one crate (`rustc_lexer`) as an example.~
