@ABataev Would it be worth resurrecting this or starting again? We have a similar test case in https://bugs.llvm.org/show_bug.cgi?id=44008

current:

  %L0 = extractelement <2 x float> %1, i32 0
  %L1 = extractelement <2 x float> %1, i32 1
  %Mul0 = fmul float %L0, 2.000000e+00
  %Mul1 = fmul float %L1, 2.000000e+00

better:

  %Mul = fmul <2 x float> %1, <2.000000e+00, 2.000000e+00>
  %L0 = extractelement <2 x float> %Mul, i32 0
  %L1 = extractelement <2 x float> %Mul, i32 1
