        * config/i386/x86-tune.def (X86_TUNE_ACCUMULATE_OUTGOING_ARGS):

We should also update comments:

   FIXME: the flags is incorrectly enabled for amdfam10, Bulldozer,
   Bobcat and Generic.  This is because disabling it causes large
   regression on mgrid due to IRA limitation leading to unecessary
   use of the frame pointer in 32bit mode.  */
