    In the NIOAPIC case, we do not need to support "legacy" irqs,
    ie; We don't need to simultaneously pass back the irq in the
    range 0 < irq < 16 (which are sometimes described as "legacy"
    in src

    This was non-obvious, until the semantics of "legacy" were
    used in inconsistent ways in Xen (to also mean interrupts in
    the 0 < irq < 256 range) which causes problems with attempting
    to unify the sys/arch/x86/isa/isa_machdep.c:isa_intr_establish_xname()
    function between XEN and !XEN

    This commit should not affect current functionality on any
    either native or Xen. It is needed for future code reorg, and
    published now as a preview.
