Write doctest tests for atomics.hpp

[cinderbdt]

I need to understand how doctest works if we're going to use it for testing. I've cloned the repo and I'm looking through the examples.

As far as I can tell, there isn't a way to write doctest cases for the header if it has no function declarations in it. Also, we don't really need them?

I think that it should be as simple as rewriting the print statements you have to be more imperative + use the test framework. What I would do is get the original atomics.h, run your file over that, then make a copy of the test file and start converting using the sizes/outputs from your original file like this:

std::cout<< "size of short: " << sizeof (short) << std::endl; -->
REQUIRE(sizeof(short) == <original atomics output>);

Does that give you more of an idea/direction?
