This changes the current default behavior (from emitting pubnames by default, to not emitting them by default) & moves to matching GCC's behavior* with one significant difference: -gno(-gnu)-pubnames disables pubnames even in the presence of -gsplit-dwarf (though -gsplit-dwarf still by default enables -ggnu-pubnames). This allows users to disable pubnames (& the new DWARF5 accelerated access tables) when they might not be worth the size overhead. * GCC's behavior is that -ggnu-pubnames and -gpubnames override each other, and that -gno-gnu-pubnames and -gno-pubnames act as synonyms and disable either kind of pubnames if they come last. (eg: -gpubnames -gno-gnu-pubnames causes no pubnames (neither gnu or standard) to be emitted) llvm-svn: 340206
