Unfortunately when building with LLVM < 15, we're using C++-11, so the std::optional bits are only available in C++-17. Even more unfortunately we can't really override this, rather inherit the fact of using C++-17 when using LLVM > 16. Thus, we add a slightly messy conditional compilation situation to allow usage of LDC on older LLVM versions, and with newer LLVM/libcxx. Signed-off-by: Ikey Doherty <ikey@serpentos.com>
