Might as well take this chance to make this public, someone may find it useful:

This is a small header file that can be used to compute VPTERNLOG immediates at compile time, via an expression that
resembles normal code (see example). It requires a modern C++11 compiler; coincidentally, most compilers that support
AVX-512F at this point also support C++11 (Intel 14.0.1+ and GCC 4.9+; Clang supports AVX-512, but does not seem to have
the intrinsics yet). You can see the resulting assembly code of  the example here:
