And nobody wants that. I'm happy to tolerate older compilers so long as it
doesn't hurt libc++'s QoI. However libc++'s ultimate consumer is the
in-tree clang it's going to be installed beside, and the implementation
should optimize for that case. Currently libc++ needs minimal C++14 support
to build the C++17 libraries and hopefully that won't change anytime soon,
but it is an inevitability as new libraries get standardized which require
new language features.
