Remove nested comments in blake2 (#4173) Replace occurence of nested comments in blake2 reference implementation with preprocessor directive for disabling unused code. `blake2s-load-xop.h` is conditionally pulled in only on chips with XOP support, among others the AMD Bulldozer. The malformed comments in the source file breaks the build of `hashlib`'s `_blake2` on GCC 6.3.0. Official reference code on github uses `#if` so this change should be uncontroversial.
