ConstantDataArray - An 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.

getString - This method constructs a CDS and initializes it with a text string.
The default behavior (AddNull==true) causes a null terminator to be placed at the end of the array (increasing the length of the string by one more than the StringRef would normally indicate. Pass AddNull=false to disable this behavior.
