Summary: cycle profiler for VM opcodes

Initial Comment:
This is just some code I'm noodling around with.  It
counts the number of cycles each Python VM opcode takes
to execute, using the Pentium timestamp counter.

I think that you should try and convince people that it is a
generally useful information to have, and that the fact that
it is highly non-portable does not hurt.  Right now it looks
more like a change that a core developer would temporarily
want to do to tune the VM.
