[$] Python interpreter adds tail calls

Description:
The Faster CPython project has been working to speed up the Python interpreter
for the past several years. Now, Ken Jin, a member of the project, has merged 
a new set of changes that
have been benchmarked as improving performance by 10% for some architectures.
The only change is switching from using computed goto statements to using
tail calls as part of the implementation of Python's bytecode interpreter  
but that change allows
modern compilers to generate significantly better code.
