FWIW, the spec calls these "abbreviation codes" and might be good to stick with that language (though the debug_info DIE code in LLVM calls them "abbreviation numbers" (in code as AbbrevNumber in the DIE, and just as "Number" in the Abbrev itself)- so I wouldn't object to that for local consistency)
