c++: fix some testcases

After r16-332 these tests started failing.  constexpr-89285.C should have
always given this error, and the new nonlit19.C needs to remove the
destructor body to prevent -fimplicit-constexpr from making the testcase
well-formed.

gcc/testsuite/ChangeLog:

	* g++.dg/cpp1y/constexpr-89285.C: Always diagnose reinterpret_cast.
	* g++.dg/cpp23/constexpr-nonlit19.C: Remove ~A body.
