Implementation of 64-bit xorshift random number generator discovered by George Marsaglia and described in his paper about Xorshift RNGs.
For 64-bit xorshift RNGs George Marsaglia proposed 275 triples, which are used here in 275 assembly functions.
These assembly functions must be parameterized with a triple and differ from the src1 functions this way, that a valid triple must be provided by the user.
The assembly files have been generated using my cppasm generator.
