Hi, Tobi, Paul and others
This is my implementation to expand powi operator to optimal multiplications.
Since there is no echo in gcc community, we had better implement it in the FE

I agree, it should be easy enough to port this to the gcc backend if need arises.

Admittedly it's not in the files themselves, so it's easily missed. But it should be included.
