What is the value of HAS_ARG going to be now?

I asked Demur to keep HAS_ARG(). Not really for backward compatibility, but for the dis module: to keep a nice assembler. There are also debug traces in ceval.c which use it.

For ceval.c, we might use HAS_ARG() to micro-optimize oparg=0 (hardcode 0 rather than reading the bytecode) for operators with no argument. Or maybe it's completly useless :-)
