[PATCH] D40231: InstructionSimplify: 'extractelement' with an undef index is undef

Hi @arsenm,

With this patch i am seeing failures in test/CodeGen/AMDGPU/indirect-addressing-si.ll . This test include extractelement instructions with undef indices, which is what this patch targets. I would appreciate your help with advice on how we can modify these tests so that they can be used safely. Please bear in mind that i have no knowledge of the AMDGPU backend.

Thanks, Zvi
