  -----------
  [SelectionDAG] Utilizing target hook convertSelectOfConstantsToMath for SelectwithConstant (#127599)

The Target hook convertSelectOfConstantsToMath() needs to be used within
SimplifySelectCC helper combine function in SelectionDAG Isel, where
generic select folding with constants is happening into simple maths op
using the condition as it is.

It necessarily fixes #121145.
