  Log Message:
  -----------
  [InstCombine] FoldShiftByConstant - merge equivalent types. NFCI.

Consistently use the original shift instruction's Type/BitWidth instead of the operands, casted values etc.

  [InstCombine] FoldShiftByConstant - create Scalar/Vector constant with ConstantInt::get(). NFCI.

There's no need to create constant vector splats manually.
