move inner optimization loop into optimize.c
The code for the inner optimization loop was in the same file
than the one for CSE. Now that the CSE have a well defined
interface, we can move this inner loop together with
the main optimization loop in optimize.c
This move make the code better structured and make it easier
to understand the optimization logic and make any experiment
or needed changes to it.
