[InstSimplify] remove poison-unsafe insertelement of undef value

PR45481:
https://bugs.llvm.org/show_bug.cgi?id=45481

SDAG has an identical transform to this, so there's little
chance of any real-world impact. OTOH, that means we are
effectively sweeping the bug out of sight because poison
exists in codegen too.
