    c++: array bound partial ordering [PR108390]

    fold_convert doesn't work with a dependent argument, and problematically
    differed from the corresponding fold+build_nop further down in the
    function.  So change it to match.

            PR c++/108390

    gcc/cp/ChangeLog:

            * pt.cc (unify): Use fold of build_nop instead of fold_convert.

    gcc/testsuite/ChangeLog:

            * g++.dg/template/partial-order3.C: New test.
