Auto merge of #84797 - richkadel:cover-unreachable-statements, r=tmandry
Report coverage `0` of dead blocks Fixes: #84018 With `-Z instrument-coverage`, coverage reporting of dead blocks (for example, blocks dropped because a conditional branch is dropped, based on const evaluation) is now supported. If `instrument-coverage` is enabled, `simplify::remove_dead_blocks()` finds all dropped coverage `Statement`s and adds their `code_region`s as `Unreachable` coverage `Statement`s to the `START_BLOCK`, so they are still included in the coverage map. Check out the resulting changes in the test coverage reports in this PR (in [commit 1](https://github.com/rust-lang/rust/pull/84797/commits/0b0d293c7c46bdadf80e5304a667e34c53c0cf7e)). r? `@tmandry` cc: `@wesleywiser`
