  Modified:    sys/i386/isa vector.s
  Log:
  Don't waste time sending an EOI to ICU1 if option AUTO_EOI_1 is defined.
  Previously, this worked right if both AUTO_EOI_1 and AUTO_EOI_2 are
  defined, but not if AUTO_EOI_1 is defined and AUTO_EOI_2 is not defined.
  The latter case should be the default.  DUMMY_NOPS should be the default
  too.  Currently there are only two NOPs slowing down rtcin() (although
  there are no delays in writertc()) and several FASTER_NOPs slowing down
  interrupt handling in vector.s.
  
  Fix stack offsets for the (previously) unused untested
  FAST_INTR_HANDLER_USES_ES case.
