  -----------
  [ValueTracking][LVI] Consolidate vector constant range calculation

Add a common helper used for computeConstantRange() and LVI. The
implementation is a mix of both, with the efficient handling for
ConstantDataVector taken from computeConstantRange(), and the
general handling (including non-splat poison) from LVI.
