fix Zulip topic for PR-creation message
add exposed-provenance example where we miss UB Example by `@saethlin`
make 'invalidate' benchmark shorter This is currently by far the slowest benchmark in our suite, taking >9s, when the second slowest takes 2.7s. So let's speed this up to 2.3s, making it still the second-slowest in the benchmark suite. `@saethlin` any objections? Also, why is this called "invalidate"? It got added in rust-lang/miri#3083 but I can't figure out the point of that name even after looking at the PR.^^ There should be a comment in the benchmark explaining what it is testing.

remove duplicate test This is basically the same as `tests/pass/imported_main.rs`.
this fixes compile_fail doctests with post-mono errors

The instrinsic is compiled to a `pause` instruction, which behaves like a no-op when SSE2 is not available. https://www.felixcloutier.com/x86/pause.html
…lfJung Allow `llvm.x86.sse2.pause` instrinsic to be called without SSE2 The instrinsic is compiled to a `pause` instruction, which behaves like a no-op when SSE2 is not available. https://www.felixcloutier.com/x86/pause.html

add support for missing SIMD float intrinsics These are being exposed by `core::simd` with rust-lang#122905.
Report retags as distinct from real memory accesses for data races This changes the error reporting for data races such that reference invariants are no longer reported as real read and writes. Before: ``` Data race detected between (1) non-atomic write on thread `unnamed-6` and (2) non-atomic read on thread `unnamed-5` at alloc1034971+0x10c. (2) just happened here ``` After: ``` Data race detected between (1) non-atomic write on thread `unnamed-8` and (2) shared reference invariant on thread `unnamed-6` at alloc1018329+0x190. (2) just happened here ``` Non-atomic read accesses from the *other* thread don't have this information tracked so those are called `some potential non-atomic read access` here.
