Rollup merge of #87761 - rusticstuff:rustc_error_overflow, r=Mark-Simulacrum
Fix overflow in rustc happening if the `err_count()` is reduced in a stage. This can happen if stashed diagnostics are removed or replaced with fewer errors. The semantics stay the same if built without overflow checks. Fixes #84219. Background: I came across this independently by running `RUSTFLAGS="-C overflow-checks=on" ./x.py test`. Fixing this will allow us to move on and find further overflow errors with testing or fuzzing.
