[dev.cc] cmd/new5a etc, cmd/internal/asm: edit to produce working Go code
These assemblers produce byte-for-byte identical output
to the ones written in C.
They are primarily a proof that cmd/internal/obj can be used
standalone to produce working object files. (The use via objwriter
starts by deserializing an already-constructed internal representation,
so objwriter does not exercise the code in cmd/internal/obj that
creates such a representation from scratch.)
