It looks like this was added here:
IIRC Abseil has a similar problem, and they chose not to support the use
case of ABI compat between TUs with different standard versions.
Personally, IMO LLVM should support this use case. I think it was a mistake
to add inline functions to Compiler.h, which is supposed to be all about
feature detection and macro definitions.
Alternatively if people want to keep things the way they are, we should
change LLVM's CMake to build with C++17 if it is supported. If the user can
link against LLVM and enable C++17, then the standard library shared by the
user and LLVM *must* have an aligned allocation function.
Either way, I don't think the user should have to do anything.
