Add a python generator for integer builtin function tests [v2]

Functions tested:
    abs, abs_diff, add_sat, hadd, rhadd, clz, clamp, mad_hi,
    mad_sat, max, min, mul_hi, rotate, sub_sat, upsample, mad24, mul24

Data Types tested:
   char, uchar, short, ushort, int, uint, long, ulong

Sizes tested:
   Scalar, Vector sizes 2/4/8/16

v2:
 - Move file into generated_tests and rename to generate-cl-int-builtins.py
 - Generate tests in cl/builtin/int (creating dir if necessary)
