  [LLVM][ConstProp] Enable intrinsic simplifications for vector ConstantInt based operands. (#159358)

Simplifcation of vector.reduce intrinsics are prevented by an early
bailout for ConstantInt base operands. This PR removes the bailout and
updates the tests to show matching output when
-use-constant-int-for-*-splat is used.
