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.
