coverage: Regression test for #117788 Without the workaround applied, this test will produce malformed mappings that cause `llvm-cov` to fail. (And if it does emit well-formed mappings, they should be obviously incorrect.)

Function name: macro_name_span::affected_function
coverage: Discard spans that fill the entire function body When we try to extract coverage-relevant spans from MIR, sometimes we see MIR statements/terminators whose spans cover the entire function body. Those spans tend to be unhelpful for coverage purposes, because they often represent compiler-inserted code, e.g. the implicit return value of `()`.

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.)
