Copy most of `tests/run-coverage` into `tests/coverage-map/status-quo` 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.

coverage: Include the highest counter ID seen in `.cov-map` dumps When making changes that have a large impact on coverage counter creation, this makes it easier to see whether the number of physical counters has changed. (The highest counter ID seen in coverage maps is not necessarily the same as the number of physical counters actually used by the instrumented code, but it's the best approximation we can get from looking only at the coverage maps, and it should be reasonably accurate in most cases.)

coverage: Simplify counter expressions using simple algebra Some of these cases currently don't occur in practice, but are included for completeness, and to avoid having to add them later as branch coverage and MC/DC coverage start building more complex expressions.

coverage: Eliminate more counters by giving them to unreachable nodes When preparing a function's coverage counters and metadata during codegen, any part of the original coverage graph that was removed by MIR optimizations can be treated as having an execution count of zero. Somewhat counter-intuitively, if we give those unreachable nodes a _higher_ priority for receiving physical counters (instead of counter expressions), that ends up reducing the total number of physical counters needed. This works because if a node is unreachable, we don't actually create a physical counter for it. Instead that node gets a fixed zero counter, and any other node that would have relied on that physical counter in its counter expression can just ignore that term completely.
