"No compiler is good enough to do what the good libraries do."
That's nonsense. And if you take a look, say, at NumPy, which uses heavily tuned BLAS/LAPACK code, and Numexpr, which uses the "compile the snippet and run it" approach, you'll see why. Libraries won't save your performance if you can't optimize across procedure and module boundaries.
