Auto merge of #89285 - jackh726:issue-88862, r=nikomatsakis
Don't normalize opaque types with escaping late-bound regions
Fixes #88862
Turns out, this has some really bad perf implications in large types (issue #88862). While we technically can handle them fine, it doesn't change test output either way. For now, revert with an added benchmark. Future attempts to change this back will have to consider perf.
Needs a perf run once https://github.com/rust-lang/rustc-perf/pull/1033 is merged
