    target/105459 - allow delayed target option node fixup

    The following avoids the need to massage the target optimization
    node at WPA time when we fixup the optimization node, copying
    FP related flags from callee to caller.  The target is already
    set up to fixup, but that only works when not switching between
    functions.  After fixing that the fixup is then done at LTRANS
    time when materializing the function.

            Rebuild the target optimization node whenever necessary,
            not only when the optimization node didn't change.
