- Closures in external crates may get compiled in because of monomorphization. We should store names of captured variables in `optimized_mir`, so that they are written into the metadata file and we can use them to generate debuginfo. - If there are breakpoints inside closures, the names of captured variables stored in `optimized_mir` can be used to print them. Now the name is more precise when disjoint fields are captured.
