Simon Pilgrim 5dc4e7c2b9 [VectorCombine] scalarizeBinop - support an all-constant src vector operand 
scalarizeBinop currently folds

  vec_bo((inselt VecC0, V0, Index), (inselt VecC1, V1, Index))
  ->
  inselt(vec_bo(VecC0, VecC1), scl_bo(V0,V1), Index)

This patch extends this to account for cases where one of the vec_bo operands is already all-constant and performs similar cost checks to determine if the scalar binop with a constant still makes sense:

  vec_bo((inselt VecC0, V0, Index), VecC1)
  ->
  inselt(vec_bo(VecC0, VecC1), scl_bo(V0,extractelt(V1,Index)), Index)

Fixes PR42174
