    gimple: Return fnspec only for replaceable new/delete operators called from
new/delete [PR98130]

    As mentioned in the PR, we shouldn't treat non-replaceable operator
    new/delete (e.g. with the placement new) as replaceable ones.

    There is some pending discussion that perhaps operator delete called from
    delete if not replaceable should return some other fnspec, but can we
handle
    that incrementally, fix this wrong-code and then deal with a missed
    optimization?  I really don't know what exactly should be returned.
