Optimize Compiler Settings

I noticed that the IR optimizer is better for all contracts **except**
the FCL library. This PR optimizes the compiler configuration to take
advantage of the IR optimizer, while adding an exception for the FCL
P-256 verifier contract so that it does not suffer any regressions.
