bugpoint reduced test case

As of r184853, running opt bugpoint-reduced-simplified.ll -loop-vectorize on
the attached input yields:

Instruction does not dominate all uses!
  %idxprom21 = zext i32 undef to i64
  %14 = getelementptr inbounds [100 x [100 x i32]]* undef, i64 0, i64
%idxprom21, i64 %13

bugpoint found this problem while I was attempting to reduce the t842 test case
from PR16431.</pre>
