Implemented assembly source generation of non-unique local labels. The new 2023-non-unique-labels test exercises various edge cases (though we're still missing local variable interaction). The format of uniquified labels changed slightly, so the expected output of 2012-label-localizer needed to be updated. This changes the "no opcode mnemonics" and "mask leading underscores" functions into integrated parts of the label localization process.
