Completes support for coverage in external crates Follow-up to #74959 : The prior PR corrected for errors encountered when trying to generate the coverage map on source code inlined from external crates (including macros and generics) by avoiding adding external DefIds to the coverage map. This made it possible to generate a coverage report including external crates, but the external crate coverage was incomplete (did not include coverage for the DefIds that were eliminated. The root issue was that the coverage map was converting Span locations to source file and locations, using the SourceMap for the current crate, and this would not work for spans from external crates (compliled with a different SourceMap). The solution was to convert the Spans to filename and location during MIR generation instead, so precompiled external crates would already have the correct source code locations embedded in their MIR, when imported into another crate. @wesleywiser FYI r? @tmandry |

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.
