The output of these tests is too complicated to comfortably verify by hand, but we can still use them to observe changes to the underlying mappings produced by codegen/LLVM. If these tests fail due to non-coverage changes (e.g. in HIR-to-MIR lowering or MIR optimizations), it should usually be OK to just `--bless` them, as long as the `run-coverage` test suite still works.
