Relevant upstream PRs:
atomic_load_seqcst,atomic_load_acquire, andatomic_load_relaxed) by a newatomic_loadintrinsic that is generic in the atomic ordering. Update the Kani code and tests accordingly.std/src/nummirrorcore/src/numrust-lang/rust#137574: Moved thenummodule fromstd/src/num.rstostd/src/num/mod.rswhich required updating the corresponding path in thescript-based-pre/verify_std_cmdtest.Resolves #4120
Call-outs:
Stringparameter of Kani'sAtomicLoadenum variant byAtomicOrdering, I opted to remove the parameter altogether since Kani doesn't do anything with it at the moment. We can easily add a parameter to that enum variant in the future if Kani needs it.atomic_loadis expected to be followed by similar changes to all atomic intrinsics.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 and MIT licenses.
