x86/x64 Instruction Level Parallelism, simple and reliable benchmarking, and then some cool machine code generated by Visual C++

A short introduction to instruction level parallelism (ILP), then how not to do benchmarking, followed by a simple and reliable way to benchmark optimized code. Using this, I identify some interesting machine code generated by Visual C++ that demonstrates ILP in practice.
