    c++: constantness of call to function pointer [PR111703]

    potential_constant_expression for CALL_EXPR tests FUNCTION_POINTER_TYPE=
_P
    on the callee rather than on the type of the callee, which means we
    always pass want_rval=3Dany when recursing and so may fail to identify a
    non-constant function pointer callee as such.  Fixing this turns out to
    further work around PR111703.

            PR c++/111703
            PR c++/107939

    gcc/cp/ChangeLog:

            * constexpr.cc (potential_constant_expression_1) <case CALL_EXP=
R>:
            Fix FUNCTION_POINTER_TYPE_P test.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/concepts-fn8.C: Extend test.
            * g++.dg/diagnostic/constexpr4.C: New test.
