    c++: Fix another crash with invalid new operators [PR117463]

    Even though this PR is very close to PR117101, it's not addressed by the
    fix I made through r15-4958-g5821f5c8c89a05 because cxx_placement_new_fn
    has the very same issue as std_placement_new_fn_p used to have.

    As suggested by Jason, this patch changes both functions so that
    cxx_placement_new_fn leverages std_placement_new_fn_p which reduces code
    duplication and fixes the PR.

            PR c++/117463

    gcc/cp/ChangeLog:

            * constexpr.cc (cxx_placement_new_fn): Implement in terms of
            std_placement_new_fn_p.
            * cp-tree.h (std_placement_new_fn_p): Declare.
            * init.cc (std_placement_new_fn_p): Add missing checks to ensure
            that fndecl is a non-replaceable ::operator new.

    gcc/testsuite/ChangeLog:

            * g++.dg/init/new54.C: New test.
