2023-11-07	coverage: Migrate `tests/coverage-map` into `tests/coverage`	Zalathar	-28/+0

2023-11-07	coverage: Flatten `coverage-map/status-quo/` into its parent directory	Zalathar	-0/+28

2023-11-07	coverage: Remove `tests/coverage-map/if.rs`	Zalathar	-9/+0
	There is another test named `if.rs` in `tests/coverage-map/status-quo/`, so this test stands in the way of flattening that directory into its parent. Fortunately both tests are more-or-less equivalent, so removing this one is fine.
2023-09-05	Add test suite `coverage-map` to test coverage mappings emitted by LLVM	Zalathar	-0/+9
	We compile each test file to LLVM IR assembly, and then pass that IR to a dedicated program that can decode LLVM coverage maps and print them in a more human-readable format. We can then check that output against known-good snapshots. This test suite has some advantages over the existing `run-coverage` tests: - We can test coverage instrumentation without needing to run target binaries. - We can observe subtle improvements/regressions in the underlying coverage mappings that don't make a visible difference to coverage reports.
