I decided to only make an `llvm::cl::opt` flag for this for now. Making a real driver flag requires a lot of plumbing to either
1) Get the value of the option to every instance of `fir::AliasAnalysis`
2) (Worse in my opinion) get the option to every call to `Fortran::lower::translateSymbolAttributes`

I didn't think it was worth complicating a lot of existing core code for this feature that nobody actually asked for. If anyone wants a real driver flag I am happy to add it.
