Add FFTW to comparison table

+# This file contains a standard list of DFT SIMD codelets.  It is
+# included by common/Makefile to generate the C files with the actual
+# codelets in them.  It is included by {sse,sse2,...}/Makefile to
+# generate and compile stub files that include common/*.c
+
+# You can customize FFTW for special needs, e.g. to handle certain
+# sizes more efficiently, by adding new codelets to the lists of those
+# included by default.  If you change the list of codelets, any new
+# ones you added will be automatically generated when you run the
+# bootstrap script (see "Generating your own code" in the FFTW
+# manual).
