Implementing Arc
In this section, we'll be implementing a simpler version of std::sync::Arc.
Similarly to the implementation of Vec we made earlier, we won't be
taking advantage of as many optimizations, intrinsics, or unstable code as the
standard library may.
This implementation is loosely based on the standard library's implementation
(technically taken from alloc::sync in 1.49, as that's where it's actually
implemented), but it will not support weak references at the moment as they
make the implementation slightly more complex.
Please note that this section is very work-in-progress at the moment.
