Removes unneeded check of `#[no_coverage]` in mapgen 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, and expanded comments and tests on one remaining issue that is still not resolved. r? `@tmandry` cc: `@wesleywiser` |

The codegen crate contains the code to convert from MIR into LLVM IR,
and then from LLVM IR into machine code. In general it contains code
that runs towards the end of the compilation process.
For more information about how codegen works, see the rustc dev guide.
