Hi,
This patch checks optab exists before using it vector vector statement 
lowering.  It fixes compilation of test from PR68062 with -funsigned-char 
option added (doesn't fix original testcase).  Bootstrapped for 
x86_64-unknown-linux-gnu.  OK for trunk if no regressions?

Thanks,
Ilya

OK.

Just curious, what was the tree code for which we couldn't find a 
suitable optab?
