c819a4c025 Don't mark ineffective_unstable_trait_impl as an internal lint 
It's not an internal lint:
- It's not in the rustc::internal lint group
- It's on unconditionally, because it actually lints `staged_api`, not
  the compiler

This fixes a bug where `#[deny(rustc::internal)]` would warn that
`rustc::internal` was an unknown lint.

033faf9499 Rollup merge of #80515 - GuillaumeGomez:js-for-loop-perf, r=Nemo157,jyn514 
Improve JS performance by storing length before comparing to it in loops

Since https://github.com/rust-lang/rust/pull/79052 is quite complicated to review, I suggested to split into smaller parts. This first part is mostly about saving the array length into a variable (I tried to not change anything else as much as possible 😃 ).

b7a9d6a51f Rollup merge of #77693 - bugadani:issue-59352, r=oli-obk 
Add test for #59352

Issue #59352 reported an optimization regression with rustc 1.32.0+. That regression could be tracked to a change that caused a function to miss the size limit of llvm's inlining, which results in an unreachable panicing branch being generated.
Enabling mir inline solves the issue, but is currently only done for `mir-opt-level>=2`.

This PR adds a test that can serve as a regression test for #59352, if/when mir inlining gets mature enough for opt-level 1, or some other optimization can remove the panic.

Remove DepKind::CrateMetadata and pre-allocation of DepNodes

Remove much of the special-case handling around crate metadata
dependency tracking by replacing `DepKind::CrateMetadata` and the
pre-allocation of corresponding `DepNodes` with on-demand invocation
of the `crate_hash` query.

5053db7c00 Don't make tools responsible for checking unknown and renamed lints 
Previously, clippy (and any other tool emitting lints) had to have their
own separate UNKNOWN_LINTS pass, because the compiler assumed any tool
lint could be valid. Now, as long as any lint starting with the tool
prefix exists, the compiler will warn when an unknown lint is present.

Choose the version of python at runtime (portable version)

r? `@Mark-Simulacrum`

Fixed version of https://github.com/rust-lang/rust/pull/80585. The goal is to avoid giving 'error: python3 required' when downloading LLVM from CI and instead default to python3 where possible.

This has some minor overhead when you have `python` as python2, but almost nothing compared to actually running the build.
