[Bug bootstrap/99983] [9/10 regression] ICE in bootstrap while building libstdc++

N.B. the original patch on trunk was by François, but the backport was done by me, with the "changes from r11-8062" which were mine and which caused the issue. I probably should have kept them separate, so François wouldn't get blamed. I didn't see this PR (and that I'd caused it) until I was CC'd in comment 9. Sorry it took so long to fix.
