<pre>This commit:
a8b9f59e8caf378d56e8bfcecdb22184cdabf42d Implement feature test macros using
a script.
added test features macros for libc++.
Among others, it added `__cpp_lib_hardware_interference_size`.
However, there is nothing like std::hardware_constructive_interference_size nor
std::hardware_destructive_interference_size, that should be in header <new>.
Unless I'm missing something, this macro should not be defined and
<a href="https://libcxx.llvm.org/docs/FeatureTestMacroTable.html">https://libcxx.llvm.org/docs/FeatureTestMacroTable.html</a> should show it as
unimplemented.</pre>
