We currently transfer the opt level from the user clang call to CC1 args at the end of the `ConstructJob` function, this might lead to bugs as `ConstructJob` is a big function and we easily could add a change that would return early from it. That would cause the opt level to not be transferred to CC1 args and lead to wrong opt level compilation and would be hard to spot. This PR moves the opt level to the beginning of the function as opt level should be a direct transfer without any problems, it also removes the redundancy where it was added 2 times through the function.
