Rollup merge of #132312 - jieyouxu:delete-crashes-23707, r=matthiaskrgr

Delete `tests/crashes/23707.rs` because it's flaky

It's conditioned on `only-x86_64` because it doesn't reliably fail on other platforms, it's optimization dependent and failed to ICE post-PGO in
<#132300 (comment)>. Remove this test for now without prejudice against relanding the test in a more reliable form.

I removed the `S-bug-has-test` label from #23707.
