Rollup merge of #122927 - gurry:122199-ice-unexpected-node-2, r=workingjubilee

Change an ICE regression test to use the original reproducer

The ICE was fixed in PR rust-lang/rust#122370, but the test used a different reproducer than the one originally reported. This PR changes it to the original one, giving us more confidence that the fix works.

Fixes #122199
