[Python-Dev] Micro-benchmarks for function calls (PEP 576/579/580)

The pyperformance benchmark suite had micro benchmarks on function
calls, but I removed them because they were sending the wrong signal.
A function call by itself doesn't matter to compare two versions of
CPython, or CPython to PyPy. It's also very hard to measure the cost
of a function call when you are using a JIT compiler which is able to
inline the code into the caller... So I removed all these stupid
"micro benchmarks" to a dedicated Git repository:
https://github.com/vstinner/pymicrobench

Sometimes, I add new micro benchmarks when I work on one specific
micro optimization.

But more generally, I suggest you to not run micro benchmarks and
avoid micro optimizations :-)
