Rollup merge of #69158 - ecstatic-morse:graphviz-diff, r=matthewjasper 
Don't print block exit state in dataflow graphviz if unchanged

A small quality-of-life improvement I was using while working on #68528. It's pretty common to have a lot of zero-statement basic blocks, especially before a `SimplifyCfg` pass is run. When the dataflow state was dense, these blocks could take up a lot of vertical space since the full flow state was printed on both entry and exit. After this PR, we only print a block's exit state if it differs from that block's entry state. Take a look at the two basic blocks on the left.

Split librustc::{traits,infer} to a separate crate rustc_infer

This is still very much work in progress.
Three functions are between dimensions (at the end of `rustc::traits`), waiting for some dependency breaking scheme.
Please tell me if the approach seems sound, and how you would like to split this PR up.

The formatting is deliberately off, to ease rebasing.

5e7af4669f Auto merge of #67885 - tobithiel:fix_group_lint_allow_override, r=Mark-Simulacrum 
rustc_session: allow overriding lint level of individual lints from a group

Fixes #58211 and fixes rust-lang/rust-clippy#4778 and fixes rust-lang/rust-clippy#4091

Instead of hard-coding the lint level preferences (from lowest to highest precedence: `lint::Allow -> lint::Warn -> lint::Deny -> lint::Forbid`), the position of the argument in the command line gets taken into account.

Examples:
1. Passing `-D unused -A unused-variables` denies everything in the lint group `unused` **except** `unused-variables` which is explicitly allowed.
1. Passing `-A unused-variables -D unused` denies everything in the lint group `unused` **including** `unused-variables` since the allow is specified before the deny (and therefore overridden by the deny).

This matches the behavior that is already being used when specifying `allow`/`deny` in the source code.

When we generate the proc macro harness, we now explicitly recorder the

3300725342 Fix running rustdoc-js test suite individually 
Without `Compiletest.path` set running `x.py test src/test/rustdoc-js` would run the `rustdoc-js` test suite with everything filtered out.

As this was the only place setting `Compiletest.path` to `None` this removes the `Option` wrapper as well.
