Paolo requested this additional test for the new __builtin_unreachable() built-in.
Go ahead after changing this:

/* { dg-options "-O2 -m32 -fomit-frame-pointer" } */

to:
/* { dg-require-effective-target ilp32 } */
/* { dg-options "-O2 -fomit-frame-pointer" } */

Why? Making that change results in the test being UNSUPPORTED on x86_64.

I now have to build and test an i686 targeted GCC to verify that it is a good test.
