Re: [RFC] More compact (100x) -g3 .debug_gnu_macro (take 4)

There seems to be some violent agreement going on here.  I think 
everyone agrees that we don't need to define anything about standard 
.debug_macro opcodes in the binary, that they will always mean the same 
thing.  The question was how to establish extended opcodes, whether via 
a define_opcode operation or in the header.
