[LLDB] Fix Clang initialization and Clang-tidy modernize-use-nullptr warnings

[Eugene.Zelenko]

Summary

Looks like RegisterContextNetBSD_x86_64.cpp should use RegisterInfos_x86_64.h as much as possible, but I think will be good idea if platform maintainer will take care about this.

[krytarowski]

There are no debug registers supported right now on NetBSD and I was forced to duplicate the code. It's on TODO and I prefer to streamline the kernel.

It's not a "C" include, if it's cstddef now. :) If you could you also move the headers to the end of the include list as well, it would be super great as that is the new style now.

Will do this in commit. I assume that headers sets comments are obsolete now too. LLVM/Clang doesn't use them.
