[PATCH] D22725: [clang-tidy] Add check 'misc-replace-memcpy'

Thanks for the reviews everyone!

I'm currently still stuck on an issue I discovered when processing LLVM. I asked for help on the mailing list [0] but maybe someone here can help. Basically the issue is that sometimes pointers are passed to memcpy for which the types are not assignable. That's okay for memcpy because it takes its arguments as void pointers, but of course this causes std::copy to complain.

I want my pass to warn the user about this issue but skip the substitution, but I don't know how to check for this case...
