Rollup merge of #131802 - compiler-errors:fnonce-coverage, r=Zalathar 
Dont ICE when computing coverage of synthetic async closure body

I'm not totally certain if this is *right*, but at least it doesn't ICE.

The issue is that we end up generating two MIR bodies for each async closure, since the `FnOnce` and `Fn`/`FnMut` implementations have different borrowing behavior of their captured variables. They should ideally both contribute to the coverage, since those MIR bodies are (*to the user*) the same code and should have no behavioral differences.

This PR at least suppresses the ICEs, and then I guess worst case we can fix this the right way later.

r? Zalathar or re-roll
