C++ PATCH for C++/71121 (wrong -Waddress warning with PMF and constexpr)

The problem here was that the code that tries to prevent the -Waddress
warning used cp_fully_fold, and later code used maybe_constant_value,
and the latter simplified the operand more so that it exposed the
ADDR_EXPR to the -Waddress warning.  Fixed by calling
maybe_constant_value from cp_fully_fold.

Tested x86_64-pc-linux-gnu, applying to trunk.
