Check that the ABI of the instance we are inlining is correct When computing the `CallSite` in the mir inliner, double check that the instance of the function that we are inlining is compatible with the signature from the trait definition that we acquire from the MIR. Fixes rust-lang#120940 r? `@oli-obk` or `@cjgillot`

Finished benchmarking commit (0e5e3ae): comparison URL. Overall result: no relevant changes - no action neededBenchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf. @bors rollup=never Instruction countThis benchmark run did not return any relevant results for this metric. Max RSS (memory usage)ResultsThis is a less reliable metric that may be of interest but was not used to determine the overall result at the top of this comment.

Could probably check that errors have been reported, but 🤷

I thought we wanted to avoid depending on global state?

still figuring out the exact details on that. But we can probably invoke the wfcheck query responsible for this 😆 not really necessary tho.
