[SG10] No __cpp_concepts in the C++20 draft

The working draft doesn't specify a __cpp_concepts macro. I want to know if
I need to say "concept bool" or just "concept", so I expected to be able to

#if __cpp_concepts
template<typename T>
#if __cpp_concepts <= 201507
  Foo = ...;

Should this be handled by a core issue?
