Execution of test gcc.dg/webizer.c fails with a segfault for
powerpc-eabi with the GNU simulator.  The test has an array of size 2
and accesses that array with indices of 1 and 2.  This patch fixes the
bounds of the loop index.

Tested on powerpc-none-eabi; OK for trunk?

Based on:


http://gcc.gnu.org/ml/gcc-patches/2012-10/msg01259.html

I think the the loop variables are fairly important.  I think we're less 
likely to perturb the test by increasing the size of the array.

Increasing the size of the array to 3 works.  OK to do that?

Yes.  That sounds good.  Please install.
