This patch implements paper P0692R1 <http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0692r1.html> from the C++20 standard.

This also fixes a bug (https://llvm.org/PR37424) where explicit instantiations of templates parameterized by overloaded private member functions were incorrectly rejected.

This is my first contribution to CFE, so please let me know if I did something horribly wrong.
