Generate openmp metadata

LLVM has an openmp-opt pass, which is part of the default O3 pipeline.
The pass bails if we don't have a global called openmp, so let's generate it if people enable our experimental offload feature. openmp is a superset of the offload feature, so they share optimizations.
In follow-up PRs I'll start verifying that LLVM optimizes Rust the way we want it.

r? compiler
add lint test

closes rust-lang#138069, which was already fixed.
Factor out diagnostic slug checking from `DiagnosticDerive`

Doing some cleanup work in preparation for rust-lang/compiler-team#959

r? @Kivooeo
ci: Move lockfile updates to a script

This makes manual tweaking a little easier when there are issues.

What is this? This is an experimental post-merge analysis report that shows differences in test outcomes between the merged PR and its parent PR.

Comparing 53b6f89 (parent) -> 158ae9e (this PR)

Test differences

Show 6 test diffs

Stage 1

  • [ui] tests/ui/lint/unused/unused_assignments_across_match_guards.rs: [missing] -> pass (J1)

Stage 2

  • [ui] tests/ui/lint/unused/unused_assignments_across_match_guards.rs: [missing] -> pass (J0)

Additionally, 4 doctest diffs were found. These are ignored, as they are noisy.

  10. aarch64-gnu-debug: 3873.1s -> 4317.8s (+11.5%)
How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
