GCC 12 should have proper support for IEEE-754 compliant 128-bit floating point in libstdc++. So warning is needed when linking against older libstdc++ versions or LLVM libc++. Glibc starts supporting float128 in both header and libraries since 2.32. Reviewed By: jsji Differential Revision: https://reviews.llvm.org/D112906
