Hi,
the ABI check miscompare was caused by inliner no longer inlining a
function
f(param)
{
  if (cond)
    external_call (param);
}
into cold regions correctly concluding that doing so would increase code
size.  However since the function is called just few times, inlining it
fully leads to code size savings by eliminating offline copy and this
fact wasn't tested in inliner. So instead of fixing the ABI check list
of symbols I am adding code to handle this in inliner.

Bootstrapped/regtested i686-linux, committed.
My apologizes for taking so long to handle this failure

	aggressive on inlining cold calls.
