And adds tests to validate it still works. There is an anticipated feature request to support a compiler flag that only adds coverage for specific files (or perhaps mods). As I thought about where that change would need to be supported, I realized that checking the attribute in mapgen (for unused functions) was unnecessary. The unused functions are only synthesized if they have MIR coverage, and functions with the `no_coverage` attribute will not have been instrumented with MIR coverage statements in the first place. New tests confirm this. Also, while adding tests, I updated resolved comments and FIXMEs in other tests.

There is an anticipated feature request to support a compiler flag that
only adds coverage for specific files (or perhaps mods). As I thought
about where that change would need to be supported, I realized that
checking the attribute in mapgen (for unused functions) was unnecessary.
The unused functions are only synthesized if they have MIR coverage, and
functions with the
no_coverageattribute will not have beeninstrumented with MIR coverage statements in the first place.
New tests confirm this.
Also, while adding tests, I updated resolved comments and FIXMEs in
other tests, and expanded comments and tests on one remaining issue that
is still not resolved.
