Marcel Moolenaar 3893a77138 Some ia32 related finetuning for the EPC syscall path: 
o  The SDM states that flushing the RSE in the cycle prior to the
   call to ia32 code yields the best performance. We don't really
   care to much about performance here, but we do the same anyway.
   I'm being paranoia and conservative here.
o  Only initialize the ia32 state registers, not the registers used
   as scratch by the ia32 engine. This saves a couple of loads from
   the trapframe, but also helps debugging: we don't clobber useful
   debugging data (engineering hints :-)
o  Make sure all general registers constituting ia32 state have been
   initialized. If there's no useful to be loaded from the trapframe,
   clear the register. This avoids accidentally leaking NaT bits.
o  Make sure we set ar.k6 prior to clobbering ar.bspstore and also
   set ar.k7 prior to setting sp. This fixes a race seen for ia64
   native code as well (and previously fixed too).
