This revision now requires changes to proceed.

Please pre-commit the baseline tests.

But we also need tests with scalable vectors - the patch will crash on this example:

  define <2 x i32> @bitcast_extelt5_scalable(<vscale x 1 x i64> %A) {
    %ext = extractelement <vscale x 1 x i64> %A, i32 0
    %bc = bitcast i64 %ext to <2 x i32>
    ret <2 x i32> %bc
  }
