[PATCH] D33467: Fix LLVM build errors if necent build of GCC 7 is used

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

This is a libstdc++ bug: https://gcc.gnu.org/PR79162 (They implemented a speculative fix for a different issue and ended up breaking this case.)

I think for now we should say we don't support building LLVM with libstdc++7.1 in C++17 mode.
