I applied your patch to ToT, but now I'm seeing a loop with the following IR (on linux). Seems still stuck in DAGCombine.

define void @test() local_unnamed_addr {
entry:

  %id34847 = alloca <2 x double>, align 16
  %id34846 = alloca double, align 8
  %id34847.0.id34847.0. = load volatile <2 x double>, <2 x double>* %id34847, align 16
  %vecext = extractelement <2 x double> %id34847.0.id34847.0., i32 1
  store volatile double %vecext, double* %id34846, align 8
  ret void

}
