ConstantDataSequential - A vector or array constant whose element type is a simple 1/2/4/8-byte integer or float/double, and whose elements are just simple data values (i.e.
ConstantInt/ConstantFP). This Constant node has no operands because it stores all of the elements of the constant as densely packed data, instead of as Value*'s.
This is the common base class of ConstantDataArray and ConstantDataVector.
