Mind adding more variants for loading floats, in addition to the variants for storing everything?

  (func (param v128 i32) (result v128)
      local.get 0
      local.get 1

      f32x4.replace_lane 0)

  (func (param v128 i32) (result v128)

Also I'd recommend running the test with/without AVX to confirm that that all works too

Sure, added additional cases, thanks! This surfaced another issue with the range-fact clamping on 128-bit values, now fixed.

The test cases already had distinct AVX and non-AVX variants; added your new cases to both.
