Switched from `std::max` to LCM for arena alignment `std::max` was indeed wrong (e.g., lcm(3,7)=21, not max(3,7)=7). One note: `llvm::lcm `doesn't appear to be available here (compiler suggested `std::lcm`, so using `std::lcm` from <numeric> (C++17). 

Happy to use a different helper if there's a preferred LLVM wrapper. Test case for LCM alignment is pending, will add in the next commit along with the test restructuring from javedabsar's feedback.
