This series of patches fixes a number of omissions and errors in the
feature test macros we define.

Tested powerpc64le-linux, committed to master.

Jonathan Wakely (8):
  libstdc++: Update value of __cpp_lib_jthread macro
  libstdc++: Remove non-standard feature test macros
  libstdc++: Add missing feature test macros
  libstdc++: Rename __cpp_lib_constexpr_invoke macro
  libstdc++: Update __cpp_lib_concepts value
  libstdc++: Do not define __cpp_lib_constexpr_algorithms in <utility>
  libstdc++: Update (and revert) value of __cpp_lib_array_constexpr
  libstdc++: Define __cpp_lib_execution feature test macro

I've backported some of these changes (and other ones related to
feature test macros) to the gcc-9 branch. This means both master and
gcc-9 should define exactly the feature test macros for the features
they support.

With that done, I've also updated the C++20 status table in the docs
(only for master so far, but I'll do it for gcc-9 too).

The attached doc patch has been committed to master.
