According to Intel's Intrinsics Guide:
this is an intrinsics for SSE2 instruction, if this is what you are asking for.
Also I guess that we should use unaligned access only where it is necessary.

I would merge this one with one blake2.h or define it where we use it.
There is already a ton of files in src directory, it would be better
to not throw in more small files like that.
