8373208: Make Atomic class template constant initializable

[kimbarrett]

Please review this change to Atomic to meet the requirements for constant
initialization in cases where the value type provides the requisite support.
This ensures that in such cases dynamic initialization won't even be
considered a possibility when initialized with constant arguments.
