Hi,
  When I was debugging a modified GCC 4.3 I ran into an ICE which was
fixed by http://gcc.gnu.org/ml/gcc-patches/2008-10/msg00217.html .
The patch did not mention it was fixing an ICE, so I decided to add a testcase.

Committed the testcase as obvious.

Thanks,
Andrew Pinski

* gcc.dg/torture/builtins-1.c: New testcase.
