Add an ensure_sufficient_stack to LateContextAndPass::visit_expr

[scottmcm]

This is apparently where it's busting stack in #112238, and the comments for ensure_sufficient_stack say that

E.g. almost any call to visit_expr or equivalent can benefit from this.

So this seems like a reasonable change.

Hopefully it'll keep this from happening in other places too -- #111818 (comment) hit something similar when updating a lint (bors failure is https://github.com/rust-lang-ci/rust/actions/runs/5199591324/jobs/9377196369), so with any luck this will keep small permutations of things from tripping over the limit.

Overall result: ❌ regressions - no action needed

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

👍

yeah if this isn't perf sensitive then I don't see why not
