lld is a linker, this PR causes clang or lld to crash inside llvm, for my case, since libc++ is built with LTO, the crash is delayed until lld performs LTO, so a standalone one-click reproducer can be generated with -Wl,-reproduce.
Since the reproducer doesn't have any libc++ headers, this probably won't help in debugging problems with lib++, but should help in understanding why the crash occurs.
