Implement support for DWARF version 5. DWARF version 5 brings a number of improvements over version 4. Quoting from the announcement [1]: > Version 5 incorporates improvements in many areas: better data compression, > separation of debugging data from executable files, improved description of > macros and source files, faster searching for symbols, improved debugging > optimized code, as well as numerous improvements in functionality and > performance. On platforms where DWARF version 5 is supported (Linux, primarily), this commit adds support for it behind a new `-Z dwarf-version=5` flag. [1]: https://dwarfstd.org/Public_Review.php

// Makes sure that `-Z dwarf-version=5` causes `rustc` to emit DWARF version 5.
tests: use minicore more minicore makes it much easier to add new language items to all of the existing `no_core` tests.
