Auto merge of #102099 - InnovativeInventor:re-cold-land, r=nikic

Rebased: Mark drop calls in landing pads cold instead of noinline

I noticed that certain inlining optimizations were missing while staring at some compiled code output. I'd like to see this relanded, so I rebased the PR from `@erikdesjardins` (PR #94823).

This PR reapplies https://github.com/rust-lang/rust/pull/92419, which was reverted in https://github.com/rust-lang/rust/pull/94402 due to https://github.com/rust-lang/rust/issues/94390.

Fixes https://github.com/rust-lang/rust/issues/46515, fixes https://github.com/rust-lang/rust/issues/87055.

Update: fixes #97217.
