    c++: consteval propagation and templates [PR115986]

    Here the call to e() makes us decide to check d() for escalation at EOF,
but
    while checking it we try to fold_immediate 0_c, and get confused by the
    template trees.  Let's not mess with escalation for function templates.

            PR c++/115986

    gcc/cp/ChangeLog:

            * cp-gimplify.cc (remember_escalating_expr): Skip function
            templates.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/consteval-prop21.C: New test.
