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.

OTOH, the patch is prepared for temporary usage, by means of

a configure option. Since nobody has been objecting

strongly, I'll accept this patch.

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.
