Don't ICE when logging unusual types MonoItemExt#to_string is used for both debug logging and LLVM symbol name generation. When debugging, we want to print out any type we encounter, even if it's something weird like GeneratorWitness. However, during codegen, we still want to error if we encounter an unexpected type when generating a name. To resolve this issue, this commit introduces a new 'debug' parameter to the relevant methods. When set to 'true', it allows any type to be printed - when set to 'false', it 'bug!'s when encountering an unexpected type. This prevents an ICE when enabling debug logging (via RUST_LOG) while running rustc on generator-related code.
